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.)
