Features/Advantages
ccurate humidity and temperature transmitters for clean rooms, harsh HVAC, and light industrial applications.
± 1.5% RH accuracy.
Easy to exchange probes on site.
Multiple calculation parameter options.
Two wire current (loop 4... 20 mA) or Modbus RTU output is optional.
TR11 series remote probe temperature and humidity transmitter TR11 can achieve accurate humidity and temperature measurement in clean rooms, harsh HVAC and light industrial applications. The shell has an IP65 protection level and is a remote probe that can be easily interchanged on site. The probe can be easily removed and replaced with a new probe without adjusting the transmitter. The transmitter can be connected to a PC for single point and multi-point calibration on site.
