2302 Hard Rod Insertion Liquid Level Transmitter Product Description
The 2302 liquid level transmitter adopts an imported silicon pressure resistance filled isolation membrane filled oil core as the signal measurement element. Based on the mathematical model relationship between the pressure, density, and liquid level of the measured liquid, the liquid level pressure proportional to the depth of the liquid level is measured by a sensor, and converted into a standard signal output through a signal processing circuit. The product has high accuracy, small size, and good anti leakage performance due to dedicated gas cables, advanced process sealing technology, reliable dedicated amplification circuits, and precise temperature compensation technology. Long term immersion in liquids ensures reliable and stable operation.

Selection Tips
1. The tested medium is compatible with the product part in contact with the medium, and it is necessary to indicate the density of the tested medium in the measurement state (excluding water)
When ordering a transmitter with an LCD or LED header, the power supply of the transmitter should not be less than 20VDC
To ensure the reliable operation of the product, it is recommended that users install lightning protection devices on site and ensure that the product and power supply are reliably grounded.
If the full range of the ordered product is less than 0.5m liquid level, our company provides products with 1.0 level accuracy.
5. Special requirements: such as strong vibration, instantaneous impact force, strong electromagnetic, and radio frequency interference, please consult with our company and indicate them in the order.
