Introduction de produit

The differential pressure transmitter combines a compensated sensing element, signal conditioning and field terminals in a protective enclosure. Selectable ranges let one hardware platform serve room pressure, filter loading and low-pressure duct applications while preserving appropriate resolution. Voltage or current output integrates with standard controllers, and selected versions add a digital network interface or local display. Removable terminals and front-access zero control simplify service without disturbing the wall-mounted tubing arrangement.

Key Features

Multiple selectable ranges adapt the transmitter to rooms, filters or duct pressure.

Stable voltage or current output provides a standard signal for PLC, DDC and EMS inputs.

Front-access zero adjustment supports maintenance without removing pressure tubing.

A protected enclosure separates field wiring from the pneumatic sensing section.

Préoccupations du client produit

A transmitter must preserve low-pressure resolution while offering field wiring, range selection and service access suitable for installed systems.

One fixed range cannot cover rooms, filters and ducts without poor resolution.Selectable full-scale ranges match the signal span to each measurement point.

A controller input requires current output but the transmitter provides voltage only.Configurable voltage and current signals support common building-control input types.

Zero checks require disconnecting tubing and rewiring the device.Front-access controls and removable terminals simplify in-place maintenance.

Condensation or dust reaches the circuit compartment through field entries.Separated pneumatic and wiring zones with sealed cable entries protect the electronics.
