Pressure Sensors available from Stock
Our broad portfolio of sensors for pressure and depth available from stock comprises models for gauge and absolute pressure sensing with variants for low pressure ranges as well as pressures of up to 400 bar. Featuring piezo-resistive ceramic technology and a microprocessor-based amplifier, these pressure sensors in a stainless-steel housing provide excellent media compatibility and are suitable for a wide range of industrial applications.
For a detailed list of all pressure sensors available, please download our pressure sensor brochure. Each pressure sensor device is temperature compensated and calibrated, requires no adjusting and provides stable signals on voltage and current outputs or even for wireless transmission to matching wireless receivers (available on demand). Custom versions of pressure ranges and outputs, process and electrical connections are available to suit your application – please contact the AMS Technologies pressure sensor experts to discuss your specific requirements.
Our IPS industrial pressure transducer series available from stock provide BSP process connection, variants for NPT process connection can be supplied on request. Options for electrical connection are DIN 43650 or M12 connectors (mating cable and plug assemblies available), and the output is calibrated in metric or psi ranges (psi output on request).
Low pressure ranges are the specialty of the IPSL series of industrial pressure transducers. With their piezo-resistive silicon sensor, giving excellent media compatibility within an oil filled 316L stainless-steel housing, these devices provide stable pressure signals especially in high vibration/shock applications. Options for electrical connection are DIN 43650 or M12 connectors.
Designed for continuous submersion in liquids such as water, oil and other non-aggressive chemicals, the ILS and ILSU series of submersible pressure sensors use the latest piezo-resistive media-isolated silicon sensing technology and a stainless-steel diaphragm within a 316L stainless-steel housing. With outputs calibrated in metric or psi ranges, the ILS and ILSU series offer excellent reliability, stability, repeatability and resolution, as required for hydrostatic level measurement in rivers and reservoirs.
Based on the popular IPS series of pressure sensors, the key benefit of the IWPT range of wireless pressure transmitters and receivers is low-cost installation for long distances as well as in inaccessible environments or on moving structures. The transmitters are easily paired to the compatible IWR family of single- (IWR-1) or five-channel (IWR-5) wireless receivers, thus offering a “plug and play” solution to your pressure measurement applications with a line-of-sight range of up to 750 m.
In addition to pressure sensors, AMS Technologies carries a broad range of further sensor solutions.
Our standard and custom liquid level sensors are designed to manage liquid levels of water, foodstuffs, chemicals and fuels in all sorts of containers and vessels. With a large range of different materials, suitable for use in many fluids including corrosive acids, vertical single- and multi-level sensors are available as well as horizontal sensors and cable-suspended versions.
Our portfolio of flow sensors is used to measure flow rates and often also the total volume of liquids flowing through a specified cross-section. With inline, paddle and ultrasonic flow sensors or switches, AMS Technologies provides solutions for a large number of applications.
AMS Technologies’ accurate and fast temperature sensors are essential for precision temperature control. Our extensive range of NTC thermistor probes provides very high sensitivity, small size and appropriate speed – perfect for use with our temperature controllers. Thermopile sensors, detectors, modules and arrays available from AMS Technologies offer leading-edge, non-contact temperature measurement for various applications – with some models additionally allowing for motion detection and presence monitoring.
Our product range of current sensors includes super high performance, lab-grade current transformers allowing non-contact measurement of currents from Microamperes to 20 Kiloamperes, at frequencies ranging from 0.5 Hz to 500 MHz.
Pressure is the force exerted by a liquid or gas on a vessel which prevents the medium from expanding. Pressure values are usually given in the form of a force per unit area or as the height of a liquid column exerting the same pressure. Pressure sensors detect this force and generate a signal proportional to the pressure acting on them – usually an electrical signal, although optical, visual or acoustic signals are also possible.
In a huge number of everyday applications, pressure sensors are used in a variety of ways for monitoring and control. In many systems, the sensors can also measure other variables such as flow, speed, water level or altitude.
Absolute pressure sensors
An absolute pressure sensor measures the pressure in relation to the theoretical, perfect pressure of vacuum (0 bar). The air pressure or atmospheric pressure, for example, is an absolute pressure and equals around 1 bar or 100 kPa at sea level.
Gauge pressure sensors
Gauge pressure sensors can be calibrated to measure the pressure in relation to the air pressure present at a given location. This makes such a sensor suitable for use in many different applications.
Sealed gauge pressure sensor
Sealed gauge pressure sensors are gauge pressure sensors by design, with the difference that the manufacturer calibrates these pressure sensors after manufacture so that they measure pressure in relation to the air pressure at sea level (1 bar).
In addition to mechanical pressure sensors that use the mechanical effects of a liquid or gas (for example by compressing a spring system) to measure the pressure of this medium, there are several other measuring principles based on technologies like strain gauges, variable capacitance, MEMS, vibrating resonators, optical fibers or piezoresistive semiconductors. The latter technique uses the piezoresistive effect of certain semiconductors to measure pressure, i.e. the change in conductivity of these materials when pressure is applied to them.
