Overview

SUCH micro differential pressure sensor is available with or without a display and supports standard, intrinsically safe, and dust intrinsically safe explosion-proof grades. Its measurement range covers 0-1kPa to 100kPa. The explosion-proof differential pressure sensor offers output signals of 4-20mA, RS485, 0-5VDC, 0-10VDC, and 1-5VDC. Its power supply voltage is selectable from 9-36VDC, 12-36VDC, or 12-24VDC (intrinsically safe). An internal air damper effectively suppresses spikes caused by pulsed pressure, ensuring stable and reliable measurement data. It is suitable for HVAC, cleanrooms, industrial process control, and environments with gas or dust explosion hazards.

Feature

Sealing design: New sealing groove with upgraded gasket for stronger protection.
Zero adjustment: Convenient button for easy self-calibration.
Air damping: Built-in device to suppress pressure spikes and improve stability.
Mounting design: Rear hidden holes for easier installation and a more elegant appearance.

Wiring Diagram

The oval represents the shield cable. All marked grounding points must be effectively grounded. Shielded twisted-pair signal cable is recommended. To prevent ground loops, the shield is grounded at one end, insulated and floating at the transmitter end, and grounded at the control cabinet end.
The transmitter housing is grounded by default, so field equipment must be effectively grounded. If grounding is not possible, ensure that the marked grounding points are effectively grounded.

FAQ

Q1: What explosion-proof options are available? ❯

The differential pressure sensor is available in three versions: Standard (non-explosion-proof), Intrinsically Safe (Ex i), and Dust Intrinsically Safe (Ex iD).

Q2: How is stability ensured in fluctuating pressure environments? ❯

The differential pressure sensor has a built-in air damping device to suppress pressure spikes and improve overall stability.

Q3: Is the explosion-proof differential pressure sensor suitable for grain processing or flour mills? ❯

Yes, the Dust Intrinsically Safe (Ex iD) model is designed for combustible dust environments like grain processing, flour mills, and feed plants.
