Veris Industries HD2XMSTA1 Transmitter

The Veris Industries HD2XMSTA1 Transmitter is a high-performance duct-mounted humidity sensor designed for precision monitoring in demanding HVACR environments. This unit serves as the direct replacement for HTSP-8542, ensuring seamless integration into existing commercial building automation systems. Utilizing a 4-20mA current loop, the transmitter provides exceptional signal stability over long distances and is engineered for an operating temperature range of -58°F to 122°F. The device features a thin-film capacitive sensor element with ±2% RH accuracy, offering rapid recovery from 100% saturation. Technicians will appreciate the field-replaceable HS element, which allows for rapid maintenance and calibration verification without disturbing conduit or wiring. Its potted circuitry prevents failure from condensate shorts, while the polarity-insensitive two-wire configuration simplifies installation for contractors and HVAC technicians. Whether managing economizer control, clean rooms, or data center climates, this analog humidity transmitter delivers the reliability required for ASHRAE standard compliance and optimal energy efficiency.

• Interchangeable HS Element: Maintain 2% accuracy with a field-replaceable sensor that eliminates the need for manual calibration in the field.
• Robust Environmental Protection: Features potted circuitry and a durable housing to withstand high-moisture air streams and temperature fluctuations.
• Streamlined Installation: Polarity-insensitive 4-20mA wiring reduces the risk of wiring errors during retrofits or new construction.
• System Compatibility: Engineered as a drop-in replacement for the discontinued HTSP-8542, maintaining existing system scaling and electrical parameters.

Is the humidity sensor element replaceable if it becomes saturated or contaminated?
Yes, the Veris HD2XMSTA1 utilizes a modular thin-film capacitive sensor. You can swap the HS element in the field to restore accuracy without removing the entire probe body from the ductwork.

Which systems are compatible with the 4-20mA output signal?
This transmitter is compatible with any direct digital control (DDC) panel, PLC, or building management system (BMS) that accepts a standard 12-30Vdc loop-powered 4-20mA analog input.

Can this unit be used in sub-zero freezer or extreme outdoor applications?
While the sensor is rated down to -58°F, it is specifically designed for duct mount applications. Ensure the housing is adequately protected from direct weather if used in air intake paths subject to external conditions.
