Model TR34 Miniature Resistance Thermometer
Brand: WIKA Alexander Wiegand SE & Co. KGResistance thermometers of this series are used as universal thermometers for the measurement of liquid and gaseous media in the range -50 ... +250 °C [-58 ... +482 °F]. The instruments are intrinsically safe and suitable for use in hazardous areas.
Features- Intrinsically safe Ex i version, very compact design, high vibration resistance and fast response time
- With direct sensor output (Pt100, Pt1000 in 2-, 3- or 4-wire connection) or integrated transmitter with 4 ... 20 mA output signal
- Integrated transmitter is individually parameterisable with free-of-charge WIKAsoft-TT PC configuration software
- Sensor element with accuracy class A in accordance with IEC 60751
