Pressure Sensor/Transmitter

Product Specifications

Technical details and manufacturing context for Pressure Sensor/Transmitter

Definition

This pressure sensor/transmitter is a component used in machinery and equipment manufacturing, specifically within a pressure regulation module. It continuously monitors system pressure and converts the physical measurement into a standardized electrical signal, typically 4-20 mA or 0-10 V, for transmission to control systems. The device employs sensing elements such as piezoresistive, capacitive, or strain gauge technologies that deform under applied pressure, causing measurable changes in electrical properties. These changes are amplified and converted into standardized output signals. The sensor is available with a measuring range of 0–1.6 MPa, accuracy of ±0.5% FS per IEC 60770, and output signal of 4–20 mA. Supply voltage ranges from 12–36 V DC, with a typical 24 V DC. Operating temperature is -40 to 85 °C, and process connection is G1/2 per DIN 3852. Ingress protection is IP65–IP67 per IEC 60529. Overpressure limit is 2× FS, burst pressure is 3× FS, and response time is ≤10 ms. Weight ranges from 0.2–0.5 kg. Wetted parts are made of 316L stainless steel per ASTM A276. Materials on file include stainless steel, ceramic, and silicon. These specifications are reference ranges; actual values must be confirmed with the manufacturer for the specific model and application. The sensor is designed for precise pressure regulation and process automation, but proper selection and verification are essential.

Working Principle

The sensor operates by exposing a sensing element to the process pressure. The element, which may be piezoresistive, capacitive, or strain gauge based, deforms under pressure, altering its electrical properties such as resistance or capacitance. This change is detected by a bridge circuit or similar electronics, amplified, and converted into a standardized output signal (e.g., 4-20 mA or 0-10 V). The output is proportional to the applied pressure and is transmitted to a control system for monitoring and regulation. The sensing element is isolated from the media by a diaphragm, often made of stainless steel, and the signal conditioning electronics are housed in a robust enclosure. The device is designed to operate within specified temperature and pressure limits, and it provides a linear output over the calibrated range.

Frequently Asked Questions

What is the measuring range of this pressure sensor?

The reference measuring range is 0–1.6 MPa. However, the actual range must be selected to cover the maximum system pressure with an appropriate margin, and confirmed with the manufacturer for the specific model.

What output signals are available?

The standard output signal is 4–20 mA, which is a two-wire loop-powered configuration. Other outputs may be available on request, but the listed specification is 4–20 mA.

What is the ingress protection rating?

The reference ingress protection is IP65–IP67 per IEC 60529. IP67 allows submersion, but the actual rating depends on the housing and connection. Verify with the manufacturer.

What materials are used for wetted parts?

The wetted parts are made of 316L stainless steel per ASTM A276. Other materials such as ceramic and silicon may be used in the sensing element. Confirm material compatibility with your media.
