Supports 2, 3, or 4-Wire RTD Sensor
The OleumTech® OTC Wireless RTD Temperature Transmitters are ideal for monitoring air, gas, water, or liquid temperatures. The WT-RT1 direct mount version is available with a 4-wire Platinum 100 ohm Class A RTD sensor with a high accuracy of ±0.15 °C / ±0.06% @ 0 °C. You can choose from 2 to 18-inch RTD length. It supports temperatures ranging from -55 °C to 260 °C. The WT-RT2 multivendor version provides a junction box and wiring terminal board for accepting a third party 2, 3, or 4-wire RTD sensor. The temperature output can be reported in Fahrenheit, Celsius, or both. These ultra-low-powered transmitters are powered by replaceable battery packs that provide up to a 10-year life. The push button LCD interface allows for device configuration and instant access to process data.
Reliable, Scalable, and Safe
The field-proven wireless transmitters communicate with an assigned wireless gateway within the OTC Wireless Sensor and I/O Network creating a highly scalable network, accommodating virtually any I/O requirement.
The OleumTech wireless transmitters are certified for use in Class I, Division 1 (Zone 0) hazardous locations. They are Intrinsically Safe, designed not to cause a spark, and can be serviced without being removed from a process.
