| The series A1 is a patent pending microprocessor based digital pressure gauge for positive, negative, and differential measurement designed to be a direct replacement for mechanical gauges. The Series A1 utilize an extremely stable piezoresistive sensing technology to give a standard full scale accuracy of 1%. For applications requiring better accuracy, the A1 is also available with 0.5% accuracy. The A1 also has an optional 4-20 mA output for applications requiring an output signal. The A1 features a bright ½" LED display, which gives the gauge improved readability and precision. The A1 also features 5 user selectable engineering units including in. w.c., mm w.c., cm w.c., kPa, and Pa. |

 The series A3 is a patent pending microprocessor based controller for positive, negative, and differential pressure as well as velocity and flow. The Series A3 includes (2) 8A SPDT relays and an associated software package that allows full configuration of variables such as setpoints, dead band, engineering units, flow coefficients, and more. The programming is done from a user friendly menu on the LCD display or uploaded using an OptiLink™ programming key. The LCD also displays the exact setpoints or other user defined variables during normal operation. Furthermore, the menu structure can be customized by moving variables to different menu levels to accommodate many applications. |

 The series A4 is a patent pending microprocessor based controller for positive, negative, and differential pressure as well as velocity and flow. The Series A4 includes (2) 8A SPDT relays and an associated software package that allows full configuration of variables such as setpoints, dead band, engineering units, flow coefficients, and more. The programming is done from a user friendly menu on the OLED display or uploaded using an OptiLink™ programming key. The OLED also displays the exact setpoints or other user defined variables during normal operation. Furthermore, the menu structure can be customized by moving variables to different menu levels to accommodate many applications. Compared to other mechanical products,
