This pressure transducer/sensor is a component used in machinery and equipment manufacturing, specifically within a leak testing module. It detects and measures pressure changes to identify leaks in sealed systems or containers, providing real-time data for quality control and process monitoring. The device operates by using a sensing element, such as a diaphragm, piezoelectric crystal, or strain gauge, which deforms under applied pressure. This deformation alters electrical properties (resistance, capacitance, or voltage), which are then converted into a standardized output signal (e.g., 4-20 mA or 0-10 V) proportional to the measured pressure. The transducer is available with a standard operating pressure range of 0–60 MPa, with custom ranges available. Accuracy is ±0.25% FS, including nonlinearity, hysteresis, and repeatability, per IEC 60770. The output signal is a two-wire loop-powered 4–20 mA, and the supply voltage is 9–36 V DC with reverse polarity protection. Operating temperature range is -40–85 °C, with a compensated range of -20–80 °C. Process connection is G1/2 per DIN 3852, and electrical connection is DIN 43650, with an optional M12 connector. Ingress protection is IP65–IP67 per IEC 60529, depending on the connector. Wetted parts are made of 316L stainless steel, with Hastelloy C optional. Weight ranges from 150–250 g, depending on connection type. Materials include stainless steel for housing/diaphragm, silicon for piezoresistive elements, and ceramic for capacitive elements. These specifications are directory reference ranges; verify model-specific values and standards with the legal manufacturer or supplier before procurement or installation.
The transducer uses a sensing element that deforms under applied pressure. This deformation changes electrical properties such as resistance, capacitance, or voltage. The change is converted into a standardized output signal (e.g., 4-20 mA or 0-10 V) that is proportional to the measured pressure. The sensing element may be a diaphragm, piezoelectric crystal, or strain gauge, depending on the design. The output signal can be used for real-time monitoring and control in leak testing applications.
