說明
The TWM11 is a versatile low-pressure and differential pressure transmitter supporting multiple output types including 4–20mA, 0–5V, 0–10V, and RS485. Its measurement range can be configured on-site (such as ±100 Pa, ±1000 Pa, ±10000 Pa), along with various selectable pressure units. Featuring an LCD with backlight, manual/auto zeroing, and adjustable response times (0.5/1/2/4 seconds), it operates on a low-power 12–30VDC supply. Designed for non-corrosive gases, the TWM11 is widely used in HVAC and building automation for filter monitoring, duct pressure measurement, and airflow-related applications. Its IP54 protection and multi-directional air inlet design allow flexible installation in diverse environments.
