High Temperature Transmitter

The LFT2030 high temperature pressure transmitter adopts a high-performance silicon piezoresistive pressure sensor, the internal dedicated integrated circuit converts the sensor's millivolt signal into a standard voltage, current or frequency signal, it can be directly connected with a computer interface card, control instrument,  intelligent instrument or PLC, etc. The distance transmission can adopt the current output mode. It has a small size, lightweight, and all-stainless steel sealed structure, which can work in corrosive environments. The product  is easy to install, has very good vibration and shock resistance, and is widely used in process control, aviation,  aerospace, automotive, medical equipment, HVAC, and other fields



Features


* High temperature resistant to 260 degrees Celsius
