Relative Humidity and Temperature Transmitters RHT-WM and RHT-DM with 4-20 mA or 0-10 Vdc outputs for temperature and humidity. Wall, duct or external probe versions for mounting. Available with ranges from -20 to +120 deg C and 0-100% RH.
Measurement Range : -40 and 120 °C / 0-100% RH (note operational limits)
Operacional limits : Electronic module(WM-DM): -20 to +65 °C, 0 to 95% RH
Operacional limits : Sensor and Probe (DM ): 0-100% RH, -20 to +100 °C (extreme -40 to +120 °C) Note: When measuring temperatures higher than +65 °C or lower than -20 °C, only 50% of the probe total length must be inserted into the measured environment
Accuracy Humidity Accuracy: ±3% RH @ 25°C Repetibility: ±1%RH Histeresis: ±1%RH Non-linearity: <<1%RH Stability: <1%RH per year
