SL6803 Negative pressure transmitterDetailed product description：

SL6803 Negative Pressure Transmitter

Negative pressure instrument - Negative pressure measuring instrument - Negative pressure transmitter, specifically used for measuring or monitoring negative pressure in boiler furnaces, flue gas ducts, and other pipelines or pressure vessels. It receives negative pressure signals from gases and converts them into 4-20mA standard current output, which is sent to computers, recorders, regulators, or variable frequency control systems to achieve fully automatic control of negative pressure Power supply voltage: 24V Output signal: 4-20 mA

characteristic
High precision: The imported sensor core is used, and precise nonlinear compensation and wide temperature compensation are carried out, resulting in high indicators of nonlinearity, hysteresis, repeatability, and temperature drift of the transmitter.
High reliability: Each transmitter undergoes 100 hours of high and low temperature aging screening before leaving the factory. The selected transmitter will have high reliability, greatly improving the mean time between failures to ensure long-term stable operation of the transmitter.
High stability: Precise temperature compensation ensures that the zero point and range of the transmitter remain stable even under large temperature changes, while the design of the floating power supply circuit allows the supply voltage to vary within 12-48V. Within this range, even significant fluctuations in power supply voltage will not affect the normal and stable operation of the transmitter.
Self protection: The overcurrent protection circuit limits the output current of the transmitter to within 25mA, which can prevent the transmitter output line from short circuiting and being damaged. The polarity protection circuit can prevent the transmitter from being damaged due to human error in power polarity connection.
