LED Digital Display Electronic Differential Pressure Transmitter Explosion Proof IP65 4-20mA Sensor

Mini Differential Pressure Transmitter with Display

This Mini Differential Pressure Transmitter integrates a high‑clarity LCD backlit display into a compact, space‑saving housing, making it an ideal choice for HVAC systems, clean rooms, air filter monitoring, and industrial process control. It provides real‑time differential pressure readings directly on the local display, eliminating the need for additional meters or handheld communicators.

Designed for air and non‑corrosive gas applications, the transmitter offers a wide measuring range from ±25 Pa up to 100 kPa with a typical accuracy of ±0.5% FS (optional ±0.25% FS). Multiple output options – 4‑20mA, 0‑10V, and RS485 Modbus – ensure easy integration into existing control systems. The device operates on a 12‑30 VDC power supply and features a fast response time of ≤10 ms. With an IP65 ingress protection rating (IP67 optional), it is suitable for both indoor and demanding outdoor environments.

Whether you need to monitor pressure drop across air filters, maintain cleanroom overpressure, or optimize HVAC duct performance, this mini differential pressure transmitter with built‑in display delivers reliable, accurate, and easy‑to‑read measurements at a competitive price.
