Model PT-1 Pressure Tester APPLICATION • For calibration, test and measurement applications requiring very high accuracy secondary transfer standards FEATURES • Simultaneously display the output of two pressure sensors, two RTD’s or one of each • 12 standard user selectable engineering units and one custom value. • Dedicated front panel buttons to set zero, check max/min values, adjust measurement damping, select either or both ports for standard display, additive or differential display, print the display and configure the RS232 output. All front panel features are accessible via the RS232 port for remote configuration or data acquisition The PT indicator is an extremely versatile pressure measurement and test instrument. Each PT indicator provides the ability to select any of twelve factory programmed engineering units, monitor and display minimum and maximum pressure values, program damping, tare out displayed measurement values and communicate over the standard RS232 interface. In addition to a broad variety of pressure ranges and types, the PT indicator can be supplied with temperature input modules. These modules provide compatibility with platinum RTD Pt100 or Pt1000 probes. The modules accommodate 2, 3 and 4 wire configurations. All these capabilities are accessible through easy-to-follow keypad functions as well as over the RS232 interface. Optional features such as the addition of a second sensor assembly, a backlit display or a built-in rechargeable battery pack make the PT indicator the ideal measurement tool for most major pressure measurement applications.
