Sensors for thermal motor protection NWT-SH This slot resistance thermometer adapts itself very well to the slot due to its flex- Slot ible form and enables a fast response behavior. The bifilar winding equalizes | induction voltages that would otherwise Slot rsistance thermometers are electric temprature sensors to measure the coil temp驩rature of electric motors, generators or transformers. They are attached directly inside the coil slots of electrical machines and are suitable for vacuum impregnation and insulated against high voltages. They offer the possibility to utilize motors close...

Sensors for thermal motor protection LT-24 The bearing thermometer LT-24 has a compact connection head, either with a clamp socket or an encapsulated supply line, and can be de-signed both as a single or double thermometer. Optionally it has a CAN-BUS interface and if desired it can be delivered with an integrated head mounted measuring transducer (4 - 20 mA). The operating temperature ranges from - 70°C to a maximum of + 180°C. Different basic sensors such as platinum measuring resistors, thermocouples or semiconductors can be built into this form. Bearing The group of screw-in rsistance...

Sensors for thermal motor protection M-OK/MH This rsistance thermometer is versatilely applicable thanks to its variable dimensions. The platinum measuring resistor is built into a stainless steel sleeve (rolled, pressed or encap-sulated) and has a permanently connected supply line. Moisture resistant and ATEX-certi-fied versions can be manufactured. Coil Resistance thermometers, based on Pt100-sensors according to EN 60751, are often imple-mented as solutions to cope with very diverse temperature measuring tasks. Our sensors are mainly utilized for the thermal supervision of coils in...

| Sensors for thermal motor protection Coil ZPTC/SH Twin thermistors in a miniature version are available with a nominal response temperature (NAT) from +60°C to +190°C. The particular NAT can be identified through the DIN-conform color coding of the PTFE-wires. Here, the NAT is +155°C. The inner connections of multiple thermistors (twin/triplet PTC) are coded yellow. A thermistor is a passive sensor whose resistance increases when the temperature rises. Due to its positive temperature coefficient it is also called a PTC-resistor. It is very well suited for monitoring a threshold...

Sensors for thermal motor protection KTY 84 / SH The shrinking tube insulated KTY silicon sensor 84 / 130, with permanently connected Teflon supply line, has a positive temperature coefficient. With a nominal value of 1000 Ohm at 100°C, it covers a major part of industrial applications. The small dimensions and an electrical strength of 2.5 kV allow a direct installation of the sensor into the copper coil. Coil Silicon sensors KTY are semiconductors that are configured similar to diodes and are used in the industrial measurement technology, the motor protection and medical technology. The...

Sensors for thermal motor protection SSH-mGS The electric band heater serves to avoid the formation of condensate, and prevents frost damage when motors are not in operation in cold environments. Electric band heaters with a glass silk tube are suitable for an installation before the impregnation process, to ensure a good adhesion and an optimal thermal coupling. Coil Electric motors that are exposed to high temperature changes or cold ambient tempratures, can incur subsequent damage caused by dew formation. An electric band heater (SSH) from Ephy-Mess helps to avoid this risk. It prevents...

Sensors for rail vehicles BM-S-KB The cable harness consists of temprature sensor, speed sensor and separation plug. It is highly shockproof, water resistant and very ro-bust. Up to four sensors can be connected to a main wire through a plug, for every cable har-ness. Temperature sensor, speed sensor as well as a shielded cable and plug connector can hereby be combined flexibly in a modular way. A plug parking place is optionally available. Traction Modest design efforts, secure operation, a low susceptibility to failures, a high availability, a fast and safe decoupling from the carriage...

Sensors for rail vehicles DWG-EM02 Speed sensor for the demanding application in rail vehicles and high-speed trains. Revolution direction and rotational speed are determined through two phase shifted channels, with the help of the incremental impulse sensor built into a brass casing. Speed sensor The speed sensors, based on incremental impulse sensors, are next to the temperature sensors a further part of the modular sensor concept of the Ephy-Mess GmbH. Through the en-coder signal the rotating direction and speed of locomotives and multiple units are detected. Ephy-Mess speed sensors are...

| Components for rail vehicles Oil level BM-S-OELSTAND Ephy-Mess oil level gauges have been patentͩe! since the year 2000 and are highly resistant against collisions due to their innovative two-chamber protection system. Repairs can be carried out on-site by the operator within a very short period of time, without the need to open the oil tank. Stone chipping in the underfloor zone of rail vehicles poses a high risk for equipment assem-blies located there. Especially critical components are hereby the oil level gauges, through which the oil level of the traction gearbox is periodically...
