Siemens 540-258 Surface Mount Temperature Sensor 8 in

Product Description

Siemens 540-258 is a surface-mount strap-on temperature sensor that uses a 100 kOhm NTC thermistor and includes an 8 in probe/cable for pipe or surface measurements. The sensor provides a 100 kOhm signal and operates over -40 to 248 F (-40 to 120 C) with an accuracy of +/-0.50 F at 77 F. It is supplied as a single hardwired unit suitable for building automation and HVAC sensing.

• 100 kOhm NTC thermistor sensing element with 100 kOhm signal characteristic
• Operating range -40 to 248 F (-40 to 120 C) with +/-0.50 F accuracy at 77 F
• Strap-on/surface-mount configuration with 8 in probe cable and hardwired connection
