Comparison between both screw connections
ADS cannot guarantee the rear clamp element will safely sit on the
screw connection if the sensor retaining element is used with an
older sensor screw connection!
To ensure safe clamping, degrease the rear area of the pipe sensor
as well as the clamping area (half-round milling groove) of the
upper and lower rear clamp elements using an appropriate method.
The sensor shaft and clamping area of the clamp elements must be
dry.
Without degreasing and drying both components and the sensor
shaft, an appropriate amount of static friction between the sensor
and sensor retaining element will not exist to safely or reliably
secure the sensor.
The retaining element included with the pipe insertion sensor from
ADS has undergone testing by an independent testing laboratory
using a long-term stress test applying 58 psi (4 Bars) constant load
and 116 psi (8.0 Bars) impact load (30 sec.). Higher pressures
cannot be applied safely!
