• Pressure ranges from 0 ... 250 mbar to 0 ... 1,000 bar
• Linearity < 0.1 % (optional 0.05 %) of span
• No additional temperature error in the range 0 ... 50 °C
• Digital data processing
• Wetted parts and case of stainless steel
• Digital output RS 232

These pressure transmitters with accuracies of 0.1 % (or 0.05%) have been designed to enable direct communication to a PC, which is especially required in the field of test, calibration and service technology. The pressure transmitter's power supply is taken directly from the RS 232-interface of the PC.

The digital data processing of the precision pressure transmitter ensures excellent values regarding linearity and repeatability. System-related temperature errors occurring usually in pressure measuring instruments are compensated by the temperature sensor integrated in the process connection and the digital data processing via microprocessor. This leads to a total temperature error of < 0.1 % in the range of 0 ... 50 °C.

All wetted parts are made of stainless steel and completely welded to exclude possible conflict between the sealing material and the pressure medium. The durable case is also made of stainless steel and provides IP 67 degree of protection.

The newly developed communication software Easy Com 2.0, which is included in delivery, allows not only the display of pressure and temperature but also the storage of the measuring data for pressure and temperature (data logger function) as well as an easy adjustment of zero point and span. The D-1X pressure transmitters also communicate as working standard through the optional Easy Cal Light software. With it, simple calibration for internal test monitoring can be accomplished.

The models of series D-11 with their flush diaphragm are particularly suitable for the measurement of media that is highly viscous, crystallizing or contains particulates. Pressure transmitters with flush diaphragm are available for the pressure ranges of 0 ... 250 mbar to 0 ... 600 bar.

Landing, NJ, January 31, 2006… American Sensor Technologies, a New Jersey-based manufacturer of state-of-the-art, MEMS-based pressure sensors, transducers, and transmitters, introduces a new media isolated, high-quality digital pressure gauge designed for use with any gas, liquid or solid media that is compatible with 17-4 PH stainless steel.

Incorporating a solid one-piece, 17-4PH high-strength stainless steel sensing element that is free of welds, internal O-rings and fluid-filled cavities, the AccuGauge Media Isolated Digital Pressure Gauge is ideal for applications that require high proof and burst pressures. Built for robust use, the transducer is packaged in a rugged NEMA 4, IP65 polycarbonate body. In addition, the AccuGauge utilizes AST's patented Krystal Bond™ Technology that further enhances its performance with long-term stability, high output and no zero shifts.

Offering user-friendly operations, the AccuGauge features four front-panel buttons that control operations. The AccuGauge can measure pressure in psi, bar, kg/cm2, inches Hg, inches H2O and ATM, making it ideal for pressure measurement of all kinds. The gauge is also vacuum-calibrated for pressure ranges under 500 PSI. A Min/Max feature allows the user to track minimum and maximum pressure readings on the digital gauge with a push of a button. The AccuGauge Zero/Tare button offers the ability to quickly reset the zero of the gauge.

A large four-digit LCD display accurately displays measurement, eliminating the guesswork related to analog dial gauges. A backlit display provides improved visibility in dark and marginally lit areas. Units operate from a 9V long-life alkaline battery that offers a typical life of 4,000 operating hours. A four-bar battery indicator on the unit display indicates a "LOW BAT" warning before the battery is fully discharged. The AccuGauge also has an automatic power-off feature to offer continuous use of the gauge before changing the battery.

The AccuGauge Media Isolated Pressure Gauge offers pressure measurement accuracy of <+0.5% of Full Scale, BFSL (including Non-linearity, Hysteresis, and Non-repeatability) over operating temperature ranges of -10º to 70ºC (-10º to 160ºF). Offering superior operations at a low price, the AccuGauge Media Isolated Pressure Gauge is priced at $250, with quantity discounts available.
