Back pressure type level switch LT1
RKC INSTRUMENT
About This Product
■Detect upper and lower limit levels of liquid with one tube
・Outputs the level when the tube tip touches the liquid surface as an alarm.
・If PFA tube is used, it can also be used with corrosive chemicals.
■High reliability
A semiconductor pressure sensor (back pressure sensor) is used in the sensor section. High reliability and reproducibility are achieved due to the structure without mechanical drive parts.
■No adjustment required
・Set the tube length to your desired length and you're ready to go.
- Built-in orifice in the main body. If you supply air gas of 20±1kPa, it will automatically reach the specified purge flow rate for the main unit.
*Other product numbers are available.
