product overview Product overview

The LPT-12 series high-temperature pressure transmitter is a pressure transmitter suitable for high-temperature applications. Compared with industrial grade pressure transmitters, the core working principle is the same. Its significant feature is good temperature characteristics, which can stably collect and measure pressure values within the range of -30 ℃~160 ℃, making up for the shortcomings of conventional pressure transmitters in high-temperature situations. Widely used in industries such as petroleum, chemical, power, metallurgy, and thermal for pressure measurement of saturated steam and high-temperature media. The output signals are diverse and can be matched with various industrial sites. The product has RS485 remote transmission function, which is convenient for remote acquisition and control.
