Product Specifications

Technical details and manufacturing context for Pressure Gauge/Sensor

Definition
This product is a pressure gauge and pressure sensor combined in one component, designed for use in machinery and equipment manufacturing. It serves as a critical monitoring element within pressure systems, detecting and measuring pressure, then either displaying the reading locally via a dial (gauge function) or converting the pressure into an electrical signal for remote monitoring and control (sensor function). By providing real-time pressure data, it supports system safety, operational efficiency, and process control. The device is available in various configurations to suit different installation and performance requirements. Typical specifications include a measuring range of 0 to 1.6 MPa (with higher ranges on request), an accuracy class of 1.0 (0.5 optional), a process connection of G1/2, a dial diameter of 100 mm (with 63 and 160 mm options), an operating temperature range of -20 to 60 °C, and an ingress protection rating of IP65. The case is made of stainless steel (grade 304, with 316L optional), and wetted parts are typically 316L stainless steel for corrosion resistance. For sensor output, the device provides a 4-20 mA electrical signal (two-wire, HART optional) and operates on a supply voltage of 12-36 V DC. The overpressure limit is 1.5 times full scale, and the weight ranges from 0.5 to 1.2 kg depending on configuration. Materials used include stainless steel, brass, Bourdon tubes (phosphor bronze or beryllium copper), diaphragms (stainless steel or elastomer), glass, and plastics such as polycarbonate and ABS. The device complies with relevant standards such as EN 837-1 for pressure gauges and IEC 60529 for ingress protection, but these are reference standards only and do not guarantee certification. Always verify model-specific values and standards with the legal manufacturer or supplier before procurement.
Working Principle
Pressure gauges typically use a Bourdon tube, diaphragm, or bellows that deforms under pressure. This mechanical deformation is translated via a linkage to move a pointer across a calibrated dial, providing a local pressure reading. Pressure sensors (transducers or transmitters) convert the same physical deformation into an electrical signal using strain gauges, piezoelectric elements, or capacitive changes. This signal is then conditioned and output as a standard industrial signal, such as 4-20 mA or 0-10 V, for remote monitoring and control systems. The choice between gauge and sensor functions depends on the application's need for local indication versus remote data acquisition.

Risk, maintenance & compliance

Reliability & Engineering Risk Analysis

Failure Mode & Root Cause
Diaphragm rupture or seal failure
Cause: Overpressure events, pressure spikes beyond rated capacity, or material fatigue from cyclic loading leading to mechanical failure of the pressure-sensing element.
Signal drift or inaccuracy
Cause: Contamination of the sensing element (e.g., process media buildup, particulates), temperature effects on electronics or materials, or degradation of internal components like strain gauges or piezoresistive elements.
Maintenance Indicators
  • Needle stuck or erratic movement (e.g., jumping, sticking at zero or max)
  • Visible fluid leakage from the gauge body or sensor housing, or audible hissing indicating a breach
Engineering Tips
  • Install a pressure snubber or pulsation damper upstream to absorb pressure spikes and pulsations, protecting the internal diaphragm or sensor from overstress and fatigue.
  • Implement regular calibration checks against a known reference standard, and ensure the gauge/sensor is rated for the specific process media and temperature range to prevent chemical attack or thermal degradation.

Frequently Asked Questions

What is the difference between a pressure gauge and a pressure sensor?

A pressure gauge provides a local mechanical display of pressure via a dial, while a pressure sensor converts pressure into an electrical signal for remote monitoring or control. This product combines both functions, allowing either local reading or remote transmission depending on the model configuration.

What are the standard measuring ranges and accuracy?

The standard measuring range is 0 to 1.6 MPa, with higher ranges available on request. The accuracy class is 1.0 for industrial use, with class 0.5 as an option. These values are reference points and must be confirmed for the specific model.

What materials are used for wetted parts?

Wetted parts are typically made of 316L stainless steel, which offers corrosion resistance for most media. Other materials such as brass or elastomer diaphragms may be used depending on the application. Always verify material compatibility with the process media.

What electrical output options are available?

The sensor provides a 4-20 mA two-wire output, with HART communication as an option. The supply voltage range is 12-36 V DC. These specifications are typical and should be verified for the exact model.
