Product Overview

Product Description and Design Advantages

Product description

The WPCK63 series is a compact pressure transmitter using a diffused silicon pressure sensor. It is lightweight, easy to install and use, and offers high cost-effectiveness.

A self-developed diffused silicon pressure sensor, highly reliable amplification circuit and wide temperature compensation convert the measured pressure into a standard output signal.

Construction and customization

The integrated all-stainless-steel structure improves corrosion resistance. The cable is protected by corrugated conduit and terminated with a standard aviation connector.

Multiple output forms and pressure interfaces are available, and customized configurations can be discussed according to application requirements.

Medium compatibility. When selecting a model, confirm compatibility between the measured medium and all product parts that contact the medium.
Specify optional requirements. When selecting non-standard options, clearly state the required configuration.
Special performance. Discuss special performance parameters or functional requirements with Winsen before ordering.
Protect the diaphragm. Do not insert hard objects into the pressure inlet; contact can cause irreparable wear to the diaphragm.
Observe the wiring definition. Do not reverse or misconnect the cable wiring. Incorrect wiring can cause malfunction or damage.
