What kind of sensors are used for heat meters?
Xin Kaixiang introduced various types of Wigan sensors. Among heat meters, flowmeters and meters, the commonly used models are WG 1 12, WG2 14, WG3 1 1.

Wigan sensor for WG2 14 multi-flow calorimeter is suitable for multi-flow calorimeter flowmeter. This product is easy to install, disassemble and output, and is equipped with a flexible cord. It is the first choice for most multi-flow calorimeters at present.

The magnetic field has high trigger sensitivity, no clutter and no signal loss. When the triggering magnetic induction intensity is 2mT( 1mT= 10Gs), the output amplitude of Wigan can reach ≥ 1.5V, and when the triggering magnetic induction intensity is 8mT, the output amplitude can exceed 3.5v.. ..

The amplitude of the output signal has nothing to do with the changing speed of the magnetic field, and the "zero speed" sensing can be realized.

The output signal can be transmitted through telephone line and coaxial line, which is suitable for LAN management.

Contactless, corrosion-resistant, moisture-proof, with a service life of more than 2 billion times.

Signal processing method for Wigan sensor of multi-flow calorimeter;

Basic application: using NPN triode to shape forward signal

This is the most basic usage and the cost is low. But the resolution of detection is slightly lower. Visual use

It depends on the requirements.
