Overview
The TL4330 zero pressure switch overcomes the common problem of pressure controllers on the market not working when the pressure drops to zero, and is suitable for low pressure alarms in the system.
The TL4330 zero pressure switch uses a diaphragm sensor that can be used for liquid media such as air, gas, water, steam, hydraulic oil, and light fuel. (If the customer uses corrosive gases or liquids, please specify in the ordering requirements.)
