Product details
Product Description
The 2301 input type liquid level transmitter uses high-performance diffusion silicon pressure sensors as measuring elements. After high reliability amplification processing circuits and precision temperature compensation, the gauge pressure or absolute pressure of the measured medium is converted into standard voltage or current signals. This product is compact in size and easy to use and install. It can be directly immersed in water to measure the liquid level height from the end of the transmitter to the liquid level.
Product Features
1. Adopting advanced circuit processing technology, with stable performance and high sensitivity;
2. Multiple measuring ranges, capable of measuring up to 200m (water column pressure);
3. Adopting 316L stainless steel isolation membrane or anti-corrosion membrane, suitable for various measurement media;
4. Flexible configuration, different configurations can be selected according to needs;
5. Integrated or split type options are available;
6. Laser resistance temperature compensation, zero point and range can be adjusted on site;
7. Wide range, corrosion-resistant, suitable for various media;
Product application
Industrial field liquid level measurement and control, urban water supply and sewage treatment, petroleum, chemical, power plants, hydrological monitoring
Measurement and control of liquid levels in fields such as reservoirs, dams, and hydropower construction.

Selection Tips
1. When selecting, pay attention to the compatibility between the tested medium and the part of the product in contact
2. There are two types of cable materials, one is a regular cable with an air duct, and the other is an anti-corrosion cable, which can be selected for use.
3. When ordering a transmitter with an LCD or LED header, the power supply of the transmitter should not be less than 20VDC
4. 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.
5. If the full range of the ordered product is less than 0.5m liquid level, our company provides products with 1.0 level accuracy.
6. 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.
