American Sensor Technologies Introduces New, Loop-Powered Digital Pressure Gauge

FOR IMMEDIATE RELEASE
(Free-Press-Release.com) May 16, 2007 -- This media-isolated, digital pressure gauge offers a 4–20mA output signal complete with a large LCD display. Utilizing AST’s Krystal Bond™ Technology, the AG200 provides the quality and performance of an AST sensor, with the additional benefits of a local readout.

The AG200 can display each of the following measuring units with the push of a button: psi, bar, kg/cm, ATM, inches H20 and Hg. The gauge also offers the option to view the 4-20mA output signal on the LCD display. By utilizing the “Test” button, the user can evaluate the loop current to ensure the system is set up correctly, as well as to adjust the current in two milliamp increments. Through the use of selecting a pressure reference, the AG200’s factory set calibration points and/or output can be reset or adjusted through a few simple steps and the factory settings can be restored at any time.

This digital pressure gauge will operate in temperatures that range from -10° to 70°C (14° to 158°F) and can be stored safely in –40° to 65°C (-40° to 150°F) temperatures. The AG200’s loop current update rate is 32 times per second along with a display update rate of 3 times per second. Additionally, the digital pressure gauge is supplied with 7.5 to 32VDC power and offers reverse polarity protection. A “Low-Loop Icon” will be displayed if the minimum power requirements are not met. The AG200 provides
