DPT-25 Differential Pressure Transmitter

Feature & Principle

It uses capacitive sensing diaphragm to detect pressure difference between high and low pressure ports. It converts tiny air pressure difference into standard analog signal for PLC or BMS controller. Zero point adjustable, anti-drift design, suitable for long-term monitoring of clean room pressure and filter clogging status.

Specifications
