12-36VDC water level transmitter with 4-20mA signal output
BH93420 I water level transmitter
Introduction :
BH93420-I Submersible water level transmitter that is based on the
characteristics of the diffused silicon sensor. The sensor is a
pressure sensor based on a silicon chip, which has a tiny
transistor structure inside it that can convert external pressure
into an electrical output.
In the diffused silicon input level transmitter, the sensor is
installed in the measuring medium. When the liquid pressure acts on
the sensor, the transistor structure inside the sensor will undergo
a small deformation, which will cause the resistance value to
change, resulting in an electrical signal output.

Ordering tips:
1. Please ensure that the measured medium is compatible with the
product components in contact with it during selection.
2. The density of the measured medium should be specified.
3. For strong electromagnetic or radio frequency interference,
please provide details to our company and indicate it in the order.
4. To ensure the reliable operation of the product, it is
recommended that users install lightning protection devices on-site
and ensure the product and power supply are reliably grounded.
