JT-2P壓力/真空傳感器
JT-2V壓力/真空傳感器
The Models JT-2P and JT-2V Loss of Pressure/Vacuum Sensor Assemblies consists of a switch, fill valve and the safety release valve. The units are used to monitor the annulus pressure/vacuum of a double-wall tank. The annulus is initially pressurized or evacuated from an external source and sealed. A leak in the secondary containment will be sensed by the transfer of the switch if the pressure falls below 1.0 psi or 1.0" Hg. Note: Before applying this type of measure, consult tank manufacturer.
