The standard self-diagnostic feature includes: • Reverse polarity detection • Signal clipping: occurs at overpressure if temperature is out of the specified range The advanced self-diagnostic feature includes: • Detection of internal transmitter failures The range of Danfoss pressure sensors also includes models with Can-Bus communication system and models for high pressure operation, up to 3000 bar. We designed our products to comply with the EU directives on EMC. In addition, we observe a range of industry-specific EMC standards, like ISO 13766 (earth-moving machinery) and DIN 40389 (EMC in road vehicles).

Our pressure sensor platform enables you to specify: • • • • • Type of electrical connection Level of accuracy Output signals Pressure connection Self-diagnostic features The piezo-resistive silicon sensor, available on most of the pressure transmitters we produce is the most suitable in applications with pressure peaks. The pressure overload is typically six times (max. 1500 bar) the measuring range and performs millions of cycles. We also offer the thin-film sensor on MBS 1200/1250 series, that allows fast response time and a compact size of the transmitter. Heavy duty versions with a damping nozzle (pulse snubber) in the pressure transducer are available to prevent dangerous cavitation and liquid hammer at the diaphragm. We designed the pressure sensor for longterm stability at temperatures of 125 °C. Moreover, the tight enclosure design ensures that the pressure transmitter is protected against moisture caused by fluctuating temperature. Our range of pressure sensors monitor themselves. A self-diagnostic feature is standard on the programmable electronics of the MBS 8250 series. More advanced self-diagnostic capabilities are also available as an option. Fig. 1: Problems with pressure surge/liquid hammer occur mainly on the outlet side after a valve or pump because of the vacuum produced by closing/shut off. Fig. 2: The damping nozzle ensures that cavitation never occurs at transmitter diaphragm. Temperature sensors meet versatile requirements Nowhere is the packaging of temperature sensors more important than in offhigh-way equipment applications. Today, Danfoss offers a versatile range of high quality temperature sensors for a multitude of applications, featuring three sensing technologies: RTD, NTC and PTC. RTD elements (Resistance Temperature Detectors) – either Pt 100 or Pt 1000 – are accurate, stable and cover a broad temperature range. Additionally, Danfoss RTD temperature sensors offer fast response times thanks to innovative design, replacing the traditional ceramic element with a thin-film element in a built-in construction. NTC’s are thermistors with Negative Temperature Characteristics while PTC’s are thermistors with Positive Temperature Characteristics. Both thermistor types are well suited for use with customized controllers and meet demands for sensors in large quantities. The thermistor is able to detect minute changes in temperature, due to the fact that the negative temperature characteristics can be as large as several percent per degree Celsius. Irrespective of your application and technological requirements, Danfoss is capable of meeting your demands with a versatile range of standard temperature sensors as well as customized sensors designed according to your specifications: 1 • OEM Temperature Sensor program • Versions with integrated plug or cable available • Various sensor elements available (RTD, NTC, PTC) • Robust, high protection against moisture • Fixed measuring insert • Brass or stainless steel • Low response times • Current or voltage output versions 0,9 ■ With fixture and heat conductive compound ■ With fixture Response time t0,5 and t0,9 0,8 0,7 0,6 0,5 0,4 0,3 0,2 0,1 0 0 5 10 15 20 25 30 ■ Without fixture 35 40 45 50 55 Response times [sec] Due to special designed element fixture the reaction time of the temperature sensor is increased dramatically. Industrial valves build quality into your product from the start In mobile hydraulic application as well as in most other industries, manufacturers often encounter the challenge of combining high performance with limited space. Danfoss direct operated solenoid valves are designed for optimum performance. Dimensions and tolerances are chosen for optimal magnetic performance and the necessary lift of the armature is designed to reduce magnetic loss to a minimum without losing performance. The armature is designed with two slots giving the fluid the possibility to be displaced quickly when the valve is activated. Mobile hydraulic equipment is often used in dusty or dirty environments. Compact valves often are sensitive to dirt due to the small dimensions. The Danfoss direct operated solenoid valves have two slots in the armature which make it possible for dirt particles to be effectively displaced to a harmless position. The pressed-in orifice is designed with an optimised sealing surface making it difficult for particles to stick and thereby give internal leaks. In addition to the direct operated solenoid valves, Danfoss has a strong and customer-oriented program of other industrial valve types, designed to suit virtually every industrial application. Thermostatically operated valve type AVTA • Self acting – needs no electricity • Exact temperature control • Insensitive to dirt – the reliable fit and forget valve • Insensitive to pressures • From zero differential pressure • Good external tightness even at high differential pressures • Broad range of different body materials, connections and temperatures • Accessories and options High performance solenoid valves types EV220B • The best water hammer damped solenoid valve • Insensitive to dirt • Broad range of different body and sealing materials • Temperature range from brine to stream • Vide coil range up to IP67 Solenoid valve type EV210A • Wide coil range up to IP65 • Compact and optimised design • Simple modular design to ensure reliable function, and easy service • Compact solenoid • Long lifetime • Less sensitive to dirt • Increased resistance against corrosion and cavitation • Optimum Kv-values • Several Kv-values for each tube sizes Long lifetime • Circular shape of the armature exactly suiting the armature tube to reduce internal wear • Valve plate resistant to extreme conditions with high temperature and pressure. Less sensitive to dirt • Two slots in the armature to displace dirt particles to a harmless position. • Pressed-in orifice is designed with an optimised sealing surface to avoid particles to stick and prevent internal leaks. Increased resistance against corrosion and cavitation • Valve orifices in stainless steel Pressure and temperature switches manage the demanding environment of mobile hydraulic equipment Off-highway equipment calls for the most stringent requirements on pressure and temperature controls. Danfoss developed a series of MBC pressure and temperature On/Off switches that fully complement our product portfolio. During design process special emphasis was placed on: • Robustness • Optimal compact design • Vibration and shock stability • Long operating life time • High switching point accuracy for repeating cycles On/Off controls can endure and work properly in the most demanding, severe environments. They are intended for alarm indication, shut down, control and diagnostics in many applications. Danfoss pressure switches operate on three different types of technology, allowing more specific monitoring of pressure. 415 A wide range of temperatures, varying from -10° to 200° C can be controlled. The sensor of MBC thermostats contains an adsorption charge. Therefore its function is not affected whether the sensor is placed in warmer or colder place then reaming part of thermostatic element (bellows and capillary). MBC 8000 thermostats can be equipped with remote sensors and standard or armoured capillary tube (for additional protection of the tube) as well as with self-supporting rigid sensor. Different sizes of sensor pockets can be ordered as accessories specially designed for our comprehensive thermostats scope. Both Danfoss pressure and temperature controlled switches are part of integrated block control program that includes also MBS sensors and MBV test valves.
