LEFOO LFT2030 high temperature pressure transmitter adopts high-performance pressure core, and the internal special integrated circuit converts the sensor millivolt signal into standard voltage, current or 485 signal, which can be directly connected with computer interface card, control instrument, smart instrument or PLC etc. to connect easily. Long-distance transmission can use the current output method. It has the characteristics of small size, light weight, all stainless steel sealing structure, etc., and can work in corrosive environment. The product is easy and simple to install, has very good anti-vibration and anti-shock performance, and is widely used in process control, HVAC, medical equipment and other fields.
Lefoo High Temperature Pressure Transmitter LFT2030 Features
* The heat sink is fully combined with the core, and it works normally at high temperature
* Adopt ASIC technology, digital compensation technology
* Excellent corrosion and wear resistance
* Strong anti-interference, good long-term stability
* Threaded connection for easy installation

High temperature pressure transmitters are used in applications where the media temperature exceeds the temperature limits of standard pressure transmitters, such as steam, food processing & engine monitoring. High temperature transducers are the most common solution for measuring pressure in hot environments, although reducing heat with a cooling element may be a better choice for some applications.
