Description
The TWM30 is a multi-output, multi-mode digital differential pressure gauge designed for versatile HVAC and automation applications. It supports 4–20mA, 0–10V, and RS485 outputs, along with dual SPDT relays for pressure control, alarms, and duct monitoring. Available in ±100 Pa, ±1000 Pa, and ±10000 Pa ranges, it offers multiple pressure units and features a backlit LCD, adjustable filtering, peak/valley display, programmable setpoints, and delay timers. With IP54 protection and multi-directional air inlets, the TWM30 is ideal for fan/blower monitoring, filter resistance detection, medical devices, and building automation systems.
