Description
The DRM108 is a micro differential pressure transmitter designed for HVAC and building automation, providing analog outputs of 4–20mA, 0–5V, or 0–10V for remote monitoring of filter status, duct pressure, and airflow-related measurements. Suitable for non-corrosive gases only, it offers both unidirectional and bidirectional ranges up to ±10000 Pa with ±1% F.S. accuracy. Built with a UL94-V0 flame-retardant industrial plastic housing and a Ø6.2 mm quick coupler, it ensures durability and easy installation. The device includes a zero-calibration button and DIP-switch-selectable response times (0.5 / 1 / 2 / 4 seconds), making it ideal for building management systems, ventilation monitoring, and precision HVAC applications.
