Series T Differential Pressure Transmitters The Series T family of differential pressure The transmitters are housed in a flame retardant, transmitters measure low pressures and feature glass-reinforced polyphenylene oxide (NORYL) low power consumption and a variety of analog case. Electrical connections are made by means of signal outputs. A wide selection of standard a 3/8 in terminal strip with 6 screws. pressure ranges and electrical ratings is available. The Series T includes four models: Model T10, These transmitters feature: no moving parts to Model T20, Model T30 and Model T40. These four wear out, reliable long term stability, and are models incorporate a variety of power and signal virtually position insensitive. options. The Series T transmitters are an excellent The span or zero adjustment is performed with a choice for many HVAC, process and automation 20-turn potentiometer for fine resolution. monitoring requirements. These transmitters monitor: filter differential pressures, fan static pressures, clean room pressures, variable air volume systems and velocity pressures. They have been used for bubbler level systems, leak detection and in medical and analytical instruments. Amphenol Advanced SensorsThe piezoresistive sensor is a solid state device designed in a Wheatstone bridge configuration. When T10 Three-wire pressure is applied to the device, the resistance of the DC Voltage In bridge changes by a small amount. This resistance DC Voltage Out change is converted to a voltage and amplified.
