Specificity
Results:
Manufacturer claims sensors will
respond to any liquid after its threshold is exceeded.
No additional materials tested.
Manufacturer’s
Specifications:
Manufacturer states that the
sensors can also be tested from their location without removal.
The test procedure is as follows: When the test button on the controller is
pressed, the normally closed light beam is opened, which simulates an actual
leak occurrence, sending an alarm signal to the controller.
The controller responds to the alarm signal by turning on an audio/visual
alarm and printing the test results.
Comments:
Optic
sensor BX-PDS also contains a conductivity sensor to determine if the product is
hydrocarbon or water.
