Gas Differential Pressure Transmitter  PEL-2500 Series

The PEL 2500 is a differential pressure transmitter specifically designed for detecting air pressure and differential pressure in air handling systems. It features temperature compensation based on ambient temperature to ensure measurement accuracy. The output signal can be selected as differential pressure or flow (volume), with a linear output characteristic.

With an IP54 protection rating, the PEL 2500 is suitable for indoor differential pressure measurement applications such as HVAC systems, as well as mechanical, system, and environmental engineering applications.

The M-type model is equipped with RS-485 Modbus RTU communication output. Parameter configuration requires the ML-SER tool for Modbus settings, and the transmitter performs periodic automatic zero calibration to maintain long-term zero-point accuracy and eliminate potential drift. It is also designed with reverse polarity protection, preventing damage caused by incorrect wiring.

The N-type model includes an integrated LCD display. The display resolution is 0.1 Pa for measurement values below 200 Pa, and 1 Pa for values above 200 Pa.
