PRD – Furneco

PRD PRESSURE TRANSMITTER

The Truflo PRD Series pressure transmitters offer several features ideal for applications where corrosion resistance is necessary.

Corrosion resistance: Available with housing materials such as Polypropylene (PP), PVDF, and 316 stainless steel to ensure durability when in contact with corrosive liquids.
Sensor and display: A ceramic or stainless steel diaphragm senses pressure changes. The device includes an LED display that changes color from green to red to provide a visual alert during an upset or alarm condition.
Outputs: Provides a standard 4–20mA output for communication with a central control system. Some models also include relay outputs (NPN or PNP) for direct alarm and control functions.
Accuracy: Available in standard (±1.0%) and precision (±0.25%) accuracy ratings.
Connectivity: Some models feature M12 connections.
