Pressure transmitter absolute pressure

• 
• Pressure Transmitter measure the pressure, negative pressure and absolute pressure of liquid, gas and steam, transfer to 4-20Madc standard current signal. Those have Gauge Pressure type(3051/3351GP) and Absolute Pressure type (3051/3351AP), can communicate with operator by HART to set and monitor.
• One side of GP type get the single of pressured ones, and another side connect to air, measure for gauge pressure and negative pressure. One side of AP type get the single of pressure ones, and another side enclose space of vacuum , measure for the absolute pressure of exhaust system, distillation tower, evaporimeter and crystallizer.
