STx Series Temperature Sensors and Transmitters are especially used for HVAC Systems as supply or extract air temperature sensors. The device can be used as limit, reference, or measuring sensor. The basic advantages are easy mounting, high protection class‐IP67, screwless electrical connector. There are many types of thermistors and RTD’s such as PT100, PT1000, NTC10k, NTC20k, NTC3k, NTC1,8k. Also transmitters have 4‐20mA, 0‐5V, 1‐5V, 0‐10V and 2‐10V outputs.

•  Maintenance free PT and NTC sensing elements
•  0…10 V output with AC 24 V or DC 13.6…34 V power supply
•  4-20 mA, 2-wired output with DC 13.6…34 V power supply
•  Simple and fast mounting
•  Screwless cover and electrical terminals
•  3 Segment display option
