Specificity Results:
Manufacturer claims sensors will respond to any liquid after sensor’s threshold
is exceeded.
Manufacturer’s Specifications:
Both of the sensors are designed
to connect to a controller system that indicates the status of the sensor.
Manufacturer indicates that
discriminating sensor ES 825-200(F) incorporates an optical liquid sensor and a
conductivity sensor. The sensor discriminates between product and water by
determining if the optical sensor, which responds to any liquid, or the
conductivity sensor, which responds only to water, causes an alarm.
