Maximum Versatility
The OleumTech® GP-TR81 is a secure, rugged, and reliable general purpose wireless transmitter designed for monitoring up to two temperature levels using RTD and or Thermocouple sensors. The
GP-TR81 supports 2, 3, or 4-wire Platinum 100 ohm RTD sensors and Thermocouple type J or K sensors. The temperature inputs can be configured independently to support any mix or combination of RTD and Thermocouple sensors.
Industrially Hardened
OleumTech wireless transmitters originated from the toughest outdoor oil and gas production locations throughout the world. They are designed to thrive in harsh, extreme weather conditions. Only the highest-grade materials go in to building our wireless instruments. The GP-TR81 is backed by a 2-year warranty.
Deploy Anywhere
The GP Wireless Temperature Transmitter can be powered using an external 9-30 Vdc source or optional SX1000-BP2 Battery Pack providing seamless flexibility. When powered by the Battery Pack, it can operate for up to 10 years before needing a battery replacement.
Scalable Solution, Easy to Use
The GP Wireless Sensor & I/O Network is comprised of a wireless gateway and wireless transmitters forming a star or point-tomultipoint network structure. Adding additional transmitters and managing I/O points are extremely simple with the OleumTech GP Network Configurator Software for PC, which is free for use to users.
