Diaphragm Pressure Sensor for Water/Viscous Liquid

5 out of 5 based on 3 reviews | Write a review

$192.69

Diaphragm pressure sensor can prevent blocking of viscous liquid. The internal ASICs convert the mV signal into a standard current (4-20mA/0-20mA), voltage (0-5V/1-5V/0-10V) or RS485 signal. Pressure sensor with stainless steel sealing structure has small size, light weight, high anti-vibration and anti-shock performance, measuring range 0~35MPa/ 0~350bar/ 0~5076psi, medium temperature -40~+60℃ (-40~+140℉), for water/viscous liquid pressure measurement.

Tips: Why the pressure sensor output signal is smaller than 4mA?
The most common reasons for maximum display is an improper selection of the pressure sensor's range or wrong setting of range, or zero shift is not made in liquid level measurement, thus making the output current of the pressure sensor to exceed 20mA. When the circuit of pressure sensor is suspected to be faulty, the circuit board can be replaced to judge the faults. Damage of the pressure sensor's diaphragm will also lead to over-range failure. For example, the output current of the diaphragm pressure sensor used for measuring vapor is greater than 20mA, and it's found after disassembling that some diaphragms have a lot of bumps, some diaphragms deform after freezing or overheated. The failure causes may be abnormal steam tracing which leads to condensate freezing, or long-term contact between the steam and diaphragm box caused by leakage. It also indirectly illustrates the importance of on-site inspection.

Existing reviews of Diaphragm Pressure Sensor for Water/Viscous Liquid

For my measurement experiment

I've had this pressure sensor for half a month. I use this sensor for my pressure measurement experiments. The sensor works well and the data is accurate. I would recommend it to my friends.

Pressure sensor works better than expected

I bought two pressure sensors of these, and both work as they should. Pretty accurate for what I am using for. The price is good and I will definitely purchase this product again!

Pressure sensors for pneumatic conveying experiments

I bought two ordinary type pressure sensors and two flat diaphragm pressure sensors. I am ready to do pneumatic conveying experiments. There is no problem with the initial inspection. I will carefully test the parameters in later experiments.
