Main product series
Differential Pressure Transmitter
Differential pressure transmitter is used to prevent the medium in the pipeline directly into the transmitter, the pressure-sensing diaphragm and the transmitter by the fluid-filled capillary tube connection. It is used to measure the level, flow and pressure of liquid, gas or steam, and then converted into 4-20mA DC signal output.
Pressure Transmitter
A pressure transmitter is a device that converts pressure into a pneumatic or electric signal for control and remote transmission. It can convert the physical pressure parameters of gas, liquid, etc. felt by the sensor of the pressure measuring element into standard electrical signals (such as 4-20mADC, etc.) to supply secondary instruments such as indicator alarms, recorders, regulators, etc. for measurement, indication and process regulation.
Valve Positioner
Valve positioner, according to the structure of the pneumatic valve positioner, electric - pneumatic valve positioner and intelligent valve positioner, is the main accessory of the regulating valve, usually used in conjunction with the pneumatic regulating valve, it accepts the output signal of the regulator, and then its output signal to control the pneumatic regulating valve, when the regulating valve is actuated, the displacement of the valve stem is fed back to the valve positioner through the mechanical device, and the status of the valve position is transmitted through the electrical signal to the upper position. system.
Flowmeter
Flowmeter English name is flowmeter, the National Science and Technology Nomenclature Review Committee defines it as: indicate the measured flow rate and/or the total amount of fluid in a selected time interval instrument. Simply put, it is used to measure the flow of fluid in the pipeline or nullah in a meter. Flowmeter is divided into differential pressure flowmeter, rotor flowmeter, throttling flowmeter, slit flowmeter, volumetric flowmeter, electromagnetic flowmeter, ultrasonic flowmeter and so on. Classification by medium: liquid flowmeter and gas flowmeter.
Temperature Transmitter
Temperature transmitter using thermocouples, RTDs as a temperature measurement element, the output signal from the temperature measurement element to the transmitter module, after regulator filtering, operational amplification, non-linear correction, V / I conversion, constant current and reverse protection and other circuitry, converted to a linear relationship with the temperature of the 4 ~ 20mA current signal 0-5V / 0-10V voltage signal, RS485 digital signal output
Radar Level Meter
Radar level meter belongs to the general-purpose radar level meter, it is based on the principle of time travel measurement instrument, radar wave running at the speed of light, the running time can be converted into level signals through the electronic components. The probe sends out high-frequency pulses that propagate at the speed of light in space, and when the pulses meet the surface of the material, they are reflected back and received by the receiver in the instrument, and the distance signal is converted into a level signal.
Manifold
Valve group is mainly divided into two valve group, three valve group, five valve group, two groups of valves is two single valves together, three groups of valves is three single valves together, five groups of valves is five single valves together.
