4-20mA 1-5V Diesel Fuel Tank Level Pressure Sensor Transmitter Transducer

Product Description

NH-93420 liquid level transmitter is based on the principle that the measured static pressure of the liquid level is proportional to the height of the liquid. It uses the diffusive silicon piezoresistive effect to convert the pressure into an electrical signal. After temperature compensation and linear calibration, it is converted into a standard Current, voltage, RS485 and other signal outputs can be directly connected to PLC / DSC, display instruments, computers, etc. Has good stability and reliability. The OEM oil-filled core is enclosed in a stainless steel housing. The front-end protective cap plays a role in protecting the diaphragm of the sensor, and can also make the liquid smoothly contact the diaphragm. The waterproof wire is hermetically connected to the shell, and the vent pipe is connected to the outside in the cable. Anti-condensation design of internal structure. HDL300 has a built-in micro signal processing circuit for remote transmission. HDL300 is widely used for liquid level measurement and control in the fields of environmental protection, water conservancy, variable frequency water supply, industrial process control, and chemical industry.
