Hot Sale IP67 Liquid NYDR RF Capacitor Switch
NYDR RF Capacitor Switch Working Principle
NYDR capacitance level switch is a highly intelligent level
measurement product, which overcomes the inconvenience caused to
customers by low alarm accuracy and complicated adjustment steps in
previous measurement methods. The RF capacitance switch is widely
used in chemical, metallurgical, petroleum, mechanical, food and
foodstuff industries.
NYDR capacitance level switch adopts advanced digital intelligent
compensation technology to convert the level change quantity in the
vessel into capacitance change quantity. Inside the probe electrode
There are two pole plates, the change of medium changes the
dielectric constant between the electrodes, so as to get the change
of electric capacity, and the electric capacity is converted into
pulse digital signal by electronic plug-in, and the design of alarm
point and the realization of alarm action are done by
microprocessor.
NYDR RF Capacitor Switch Design Feature
1.This product uses intelligent microprocessor components and
differential measurement technology, can measure water, sewage,
mud, and other liquids, especially effective and accurate
measurement of strong corrosive media, can be dynamic compensation
for environmental changes and hanging material.
2.This product can be used in non-metallic tank sensor built-in
subsidized electrode, and don’t need to add electrode inside the
container.
3.The operation is very simple, only need to adjust the
corresponding sensitivity knob according to the media, and wave
surge delay filtering can be used.
4.The upper limit and lower limit alarms can be set flexibly, and
the user can set and select the normally open and normally closed
contacts.
5.Both single-point and multi-point relays use high performance
imported single-blade double-throw relay, single-point contact
current capacity up to 8A, multi-point 3A. It can directly drive
the range of alarm devices.
6.Using PTFE probe, detection parts without moving devices, impact
resistance, high temperature resistance, corrosion resistance.
