Sensor can be cut in the field to accommodate various size assemblies.

Originally, the Worm sensor from Moore Industries, North Hills., Calif., was designed as a sensor that could be cut in the field to accommodate various size assemblies. But on-the-job users quickly found other ways to put the sensor to work. Here are some examples.

Over time, the inside of wells may accumulate dirt, mineral deposits and corrosion scaling. If you start with a 0.25” OD sensor and a 0.26” ID well, for instance, then add debris, just getting the sensor in or out of the well becomes difficult, if not impossible. But the flexible sensor's outer diameter of just 0.237” allows it to slide past debris.

Wells that are installed horizontally have a tendency to sag with time and temperature. While removing and reinserting a rigid sensor can present challenges, the Moore sensor has a flexible design that permits it to slide into sagging wells.

With a sheath length of only 1.5" instead of a long solid sheath of straight sensor, the Worm offers response times 30 percent faster than straight sensors, according to Moore Industries. Fast response offers advantages when measurement speed is essential.

The sensor's flexibility also delivers enhanced durability in high vibration applications. Replacing failed straight sensors is easy and fast because the sensor can slide into an enclosure without requiring removal of assembly components.

Moore Industries has released a video that demonstrates these features that can be viewed at
