Interior Temperature Sensors for Railway Vehicles
In response to increasing air quality requirements, SENSIT is introducding a new line of interior temperature sensors for railway vehicles.
Based on their customer’s ever growing requests for modification and innovation of the temperature switch designed for railway vehicles, SENSIT s.r.o. have set to innovate and modernise the original KTSZ3H temperature switch. Therefore, they would like to present to you their new KTSZ4H temperature switch.
The KTSZ4H temperature switch, naturally, meets the railway regulations according to the EN 50155, EN 50121-3-2, EN 61373 and EN 45545-2 standards. They can also produce the temperature switch in a variant meeting the NFPA 130 standard.
The KTSZ4H temperature switch is designed as a two-state controller (ON/OFF control) which compares a set temperature value with measured temperature, and when the set temperature value is reached, it enables switching the galvanically separated contacts. The switch supply voltage is 10 to 33 V DC/9 to 24 V AC. Up to 2 temperature sensors can be connected to the switch. During measuring, the switch screen gradually displays instantaneous temperature values from both sensors. Individual parameters can be set using two control buttons.
Each function can be set with a time delay for relay opening (for relay 1) in the range from 0 to 300 s. The switches are designed for mounting on a DIN rail. The maximum temperature range of sensor use is -50 °C to 400 °C. The standard inputs of the switch are Pt 100/3850 and Pt 1000/3850. Alternatively, the switch can be offered with an Ni 1000/6180 input.
We are currently designing a KSTH 120 temperature and relative humidity sensor for temperature and humidity measurement in air-conditioning ducts. The sensor will be provided with a digital RS 485 (MODBUS) output or CAN protocol output.
Also, we are working on liquid and air flow sensors. We will try our best to get everything ready for Innotrans 2020 in Berlin.
