Transmisor de presión diferencial
A wall-mounted transmitter that converts low differential pressure into a stable analog or digital signal for cleanroom controllers and monitoring systems.
- Field-Selectable Pressure Ranges
- Analog and Network Outputs
- Stable Zero Reference
- Service-Friendly Enclosure
Introducción del producto
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.
Características clave
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.
Preocupaciones del producto del cliente
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.
