Product Manual
This advanced micro differential pressure transmitter/controller combines measurement, display, and control in one intelligent unit. Designed with a high-precision MEMS digital pressure sensor, it accurately detects positive, negative, or differential pressure—making it ideal for precise gas pressure monitoring in cleanrooms, HVAC systems, laboratories, and ventilation control.
The device features an easy-to-read LCD screen with switch control and analog or digital signal output options (4–20mA, 0–10V, or RS485 with Modbus RTU). It also includes an adjustable relay switch with configurable action points, multiple pressure units, and a digital damping filter for real-time, flexible adjustments in the field.
With a flame-retardant ABS housing and built-in buzzer alarm, this unit is durable, responsive, and ideal for critical low-pressure air or gas detection scenarios where stability and reliability matter.
