Ürün tanıtımı

This differential pressure sensor uses one temperature-compensated ceramic sensing element to compare the air pressure applied to two separate hose ports. The compact non-display enclosure keeps the measurement electronics behind a gasketed service cover, while one green indicator reports basic operating status without turning the device into a local digital gauge. A bottom compression gland routes the supply and output conductors to a four-position screw terminal, and a four-switch selector bank supports the configured range or response setting. Four reinforced mounting holes secure the transmitter to a wall, duct panel or control backplate. The connected tubing, measurement span, supply voltage and output signal are chosen together for room-pressure, airflow or filter-loading duty.

Ana Özellikler

Two physically separate hose barbs maintain distinct high- and low-side pressure paths, reducing the chance of confusing a differential measurement with a single static-pressure input.

A compact ceramic sensing element supports low-pressure air measurement without the mechanical pointer, movement and viewing window of an analog gauge.

The sealed polymer housing provides one controlled cable entry and a removable front cover for terminal access while keeping the normal installed face simple and easy to wipe.

Selectable span and response settings allow one enclosure format to serve room pressurization, filter condition or duct airflow monitoring when paired with the correct output configuration.

Müşteri Ürün Sorunları

Low differential-pressure measurements are sensitive to tubing errors, unsuitable range selection and mounting conditions, so the complete pressure path and electrical signal must be checked as one measurement loop.

Reversing the two pressure tubes makes the measured direction incorrect and can cause a control system to interpret a positive room pressure as negative.The high and low connections are identified by fixed color rings, and both tube routes are traced from the room or duct pickup points before energizing the loop.

A span that is much wider than the expected pressure difference reduces useful resolution around the operating setpoint.The configured pressure range is chosen close to the normal and alarm limits while retaining enough margin for startup and filter-loading excursions.

Kinked, leaking or moisture-filled tubing can create slow response, offset or apparently stable but false readings.Both hoses use equal, supported runs with airtight joints, open pickup tips and suitable routing that prevents sharp bends and trapped condensate.

Incorrect supply or output wiring can produce a valid-looking signal that is scaled differently from the receiving controller.Supply voltage, 4-20 mA or 0-10 V output type, terminal assignment and controller scaling are verified together before the value is used for alarms or control.
