About the AGS4400 High-Pressure Transducer

The GENSPEC AGS4400 pressure transmitter is designed to meet the operational requirements of demanding pressure measurement applications where good quality, fast delivery and low cost are of the highest priority.
Providing a half-duplex digital RS-485 output signal and 0-5V analog output, the AGS4400 provides high stability and repeatability. It can be configured to suit a multitude of applications and with proprietary RS-485 protocol, each sensor can be allocated a unique device address and connected in series to other sensors and devices on the same communications link.

The unique Silicon-on-Sapphire sensor technology provides outstanding performance and gives excellent stability over a wide temperature range. The advanced sensor design consists of a piezoresistive silicon strain gauge circuit, which is epitaxially grown onto the surface of a sapphire diaphragm to form a single crystalline structure. The sapphire sensor element is then molecularly bonded to a titanium alloy sub-diaphragm. This enables the sensor to endure higher over-pressures and provides superb corrosion resistance. The sensor exhibits virtually no hysteresis and excellent long-term stability. With outstanding insulation properties, the sapphire substrate allows the sensor to operate over a very wide temperature range without loss of performance.

Standard digital accuracy is 0.15%, with an exceptional overpressure limit. All models are supplied with integral 1/4”BSP male with a range of other process connection options. The titanium alloy wetted parts offer unbeatable corrosion resistance and the M12 electrical connection is rated IP67 for high levels of environmental protection.
Applications for the AGS4400 include the continuous monitoring of hydraulic systems with oil, gas, water and other process liquids, industrial, medical and aerospace industries. Also ideal for the measurement and control of pressure in refrigeration, pneumatic, compressor, HVAC and engine monitoring systems.
