Description

Achieve precise, reliable environmental monitoring with a compact transmitter series built for both wall and duct installations. Engineered with high-accuracy, long-term stability humidity and temperature sensors, these devices convert measurements into linear 4–20 mA signals for seamless integration with industrial and building automation systems. A microprocessor-based design enables full configuration of output ranges via the TxConfig PC interface and Windows® software, ensuring fast commissioning and flexible setup.

Choose the mounting style that fits your application—wall for ambient monitoring or duct/through-the-wall for HVAC and process air. The humidity channel can be configured for relative humidity or dew point output, giving you the versatility to meet comfort, process control, or critical environment requirements.

Main Features:

Power supply: 12 to 30 Vdc (loop-powered 4–20 mA)
Outputs:
- Two-wire 4–20 mA or 20–4 mA
- Isolated 4–20 mA outputs with isolation between channels
Output load (RL):
- For 4–20 mA: RL (max, Ohms) = (Vdc – 12) / 0.02
Internal protection against reversed polarity
Cable entry: PG7 cable gland
Operating limits:
- Electronics: -10 to +65°C, 0 to 95% RH

Designed for dependable performance in HVAC, clean rooms, process control, and facility monitoring, this transmitter delivers stable readings, robust 4–20 mA signaling, and straightforward installation. Configure for relative humidity, temperature, or dew point to optimize control strategies and improve energy efficiency.
