Temperature sensors to electric motor windings


Temperature sensors of high electric strength and mechanical durability for measuring temperature in electric motor windings, bearings, transmissions 

Cable resistance temperature sensors encapsulated in metal housing or in heat-shrink tube. These temperature sensors operate in various temperature ranges from -50 °C to 260 °C (according to temperature sensor type). The most common sensing elements are Pt 100, Pt 1000, Ni 1000, KTY, NTC, PTC. 

Temperature sensors are most frequently used for measuring the temperature of electric motor windings (sensors with insulation of shrink tube), measuring the temperature in bearings, measuring the temperature of engine oil, measuring the temperature in transmissions and other. Other applications Snímače teploty do vinutí elektromotorůof these temperature sensors can include temperature measurements in laboratories and in testing facilities, measurements of temperature of solid, liquid and gaseous substances. Temperature sensors have high electric strength up to 12 kV, according to sensor type (electric strength can be even higher if requested).

Temperature sensors comprise the sensing element Pt 100 or Pt 1000, but they can also be fitted with thermistors NTC or PTC, and even KTY. Cables or conductors are connected with the sensing element (various types according to application and customer’s request) and encapsulated in metal housing or heat-shrink tube. Measuring ranges of the sensors vary according to the type of application.

Temperature sensors into electric motor windings - temperature sensors insulated by heat-shrink tube TR 097x type 

Cable temperature sensors whose housing comprises a heat-shrink tube. These sensors are distinguished for their high electric strength (5 kV - it can be even higher if requested) and their most common application is measuring the temperature in electric motor windings.

Basic parameters of temperature sensors insulated by heat-shrinking sleeve:

  • Sensing element: Pt 100, Pt 1000, Ni 1000, NTC, PTC, KTY, other as requested 
  • Temperature range of use: temperature class H -20 °C to 180 °C 
  • Lead-in wires: teflon FEP or PFA 0.22 mm2 
  • Electric strength: 5 kV 
  • Ingress protection: IP 20 
  • Connection: 2wire, 3wire or 4wire 

Parameters and design of the sensor may be adjusted as requested. 


Temperature sensors into electric motor stator slot TR 097V type 

Cable temperature sensors with the housing made of Sklotextit frame and heat-shrink tube. These temperature sensors are distinguished for their high electric strength (12 kV) and most frequently used for measuring the temperature in the slot of the electric motor stator.

Basic parameters of temperature sensors insulated by heat-shrinking sleeve:

  • Sensing element: Pt 100, Pt 1000, Ni 1000, NTC, PTC, KTY, other as requested 
  • Temperature range of use: temperature class H -20 °C to 180 °C 
  • Case: Sklotextit frame covered with heat-shrinking sleeve 
  • Lead-in wires: teflon APFA 
  • Electric strength: 12 kV 
  • Ingress protection: IP 65 
  • Connection: 2wire, 3wire or 4wire 
Parameters and design of the sensor may be adjusted as requested. 

Temperature sensors for measuring temperature in bearings, engine oil, transmissions 

Resistance temperature sensors encapsulated in the housing of stainless steel DIN 1.4301. The diameter of the housing is 1.5 mm. Thermal resistance of the sensors is up to 400 °C, depending on the selected type of input cable. IP protection of the sensors can be up to IP 68. The design of the sensors depends on the application and can be with smooth metal case, with threading, contact temperature sensors, temperature sensors with bayonet lock, temperature sensors with connector, right-angle temperature sensors. The temperature sensors utilize the technology ensuring their higher resistance against impacts and vibrations. Stainless protection tube can be used as a protective element of lead-in wires.

The temperature sensors with bayonet lock ensure permanent thrust of the sensor onto the measured place, protecting the sensor against mechanical damage if the object being measured is vibrating. Also, it ensures better reading of temperature.

Veryfied and Reliable Temperature Sensors

Verified and reliable temperature sensors Dear customers, We would like to let you in on what happens to temperature sensors before they are packaged and shipped to you. After manufacturing, all temperature sensors are labelled with their own unique identification code and the entire batch is put into cycling chambers. In the chambers, the sensors undergo 7 to 10 temperature cycles from -10°C to 120°C depending on the sensor type. With this so-called burn-in (or ageing) process, we simulate the load on the sensor to detect any critical manufacturing defects.
