Product Description

Product description

A switch contact composed of multiple contacts can also be set as a single set point. When the actual value pointer  moves beyond or below the desired set point, contact actuation will be performed.

The pressure gauge is manufactured in accordance with DIN 16085 and meets all requirements of relevant standards (EN  837-1) and on-site display regulations for pressure vessel working pressure.

As switch contacts, there are magnetic quick acting contacts, reed switches, and electronic contacts to choose from.  To trigger a programmable logic controller (PLC), electronic contacts and reed switches can be used.


Special Features

  • High reliability and long service life.

  • Each instrument has a maximum of 3 switch contacts.

  • Instruments with electronic contacts for PLC applications.

  • Contact gauge complies with DIN 16085 standard.


Application

  • Control and regulation of industrial processes.

  • Monitoring of plants and switching of circuits.

  • Suitable for gaseous and liquid media with low viscosity or non crystallization that will not corrode copper alloy      parts.


Core Advantages

  • Reliable and Durable: Stainless steel case with high-quality contacts, ensuring long-term stable performance in      industrial environments.

  • Function Integration: Dual-purpose gauge, capable of pressure measurement and circuit control simultaneously to      reduce costs.

  • Flexible Adaptation: Multiple contacts with full-range adjustability, suitable for complex interlock logic.

  • PLC Compatibility: Electronic electrical contacts are optional for direct connection to low-voltage PLC signals.

  • Safety and Compliance: Compliant with DIN/EN standards, and some models come with ATEX explosion-proof      certification.

Pressure Transmitter FAQ

What is a pressure transmitter used for?

A pressure transmitter converts the pressure of liquid, gas or steam into a standard electrical signal for PLC, DCS, recorder or control instrument input. It is widely used for pipeline pressure, tank level, flow measurement and process safety monitoring.

How do I choose the right pressure transmitter?

Confirm the pressure range, pressure type, medium, temperature, output signal, accuracy, installation thread, electrical connection and environmental requirements. For corrosive media, high temperature or sanitary applications, diaphragm material and sealing structure are especially important.

What is the difference between gauge, absolute and differential pressure transmitters?

Gauge pressure transmitters measure pressure relative to atmospheric pressure. Absolute pressure transmitters measure pressure relative to vacuum. Differential pressure transmitters measure the pressure difference between two points and are commonly used for flow, filter and level measurement.

Can Xinyi Instrument provide customized pressure transmitters?

Yes. Xinyi Instrument can support customized pressure ranges, process connections, output signals, cable length, display options and model selection for different industrial applications.
