Test institute confirms exceptional quality under extreme conditions

JUMO Train Sensor Awarded "Environmental Testing" Certificate According to EN 50 155

Measurement technology in railway vehicles is often subjected to extreme loads. A test conducted by the Swiss Quinel institute has now provided impressive confirmation that the JUMO screw-in RTD temperature probe with bayonet connector for railway technology fulfills even the most stringent requirements.

The 902815 model was tested according to the EN 50 155 standard for the railway industry and easily met the requirements for the institute's Environmental Testing Certificate. Among other things, this standard guarantees that the product can be used at an ambient temperature between -50 and +85 °C. To verify this, the screw-in RTD temperature probe was subjected to intense temperature tests as well as an extensive range of vibration and shock tests according to EN 61373.

The compact RTD temperature probe model 902815 comprises a protection tube with an integrated temperature sensor, a process connection, and an attached housing for the transmitter electronics. The integrated two-wire transmitter can be programmed and converts the temperature value into a current signal of 4 to 20 mA.

The screw-in RTD temperature probe can be used to measure temperatures from -50 to +150 °C and up to +260 °C when used with an extension tube. When used without a transmitter the potential temperature range is -50 to +260 °C. The output signal of 4 to 20 mA or reversed 20 to 4 mA is available in temperature-linear form.
