Gems® type 3G fittings are designed for general purpose use, and are made of PVC to withstand corrosive conditions. The flanged assemblies are sized to accommodate up to seven probes and to mate with standard flanges on the tops of vessels.
Gems® type 3F flanged, pressure-tight fittings are designed for general purpose service and can handle up to seven probes. They mate with standard pipe flanges coupled to the top of the vessel. They are available in a variety of materials.
Gems® type 16 open circuit board controls are engineered for general purpose single-level or differential applications. They feature spade terminals for easy wiring and provide sensitivities up to 1 million ohm/cm. The 16D has the same features and specifications as the 16, but also has DPDT load contacts to eliminate the need for slave relays. Common applications include single-level service, point level, valve control, low-water cutoff, differential service, alarms, and pump control.
Gems® type 3R probes are metallic rods with threaded ends that screw into a fitting that extends vertically down into the liquid. They are available in a variety of materials for different applications. Series 3T are tapered rods. Both are for general purpose use.
Gems® type 3E fittings are cast metal, pressure-tight assemblies capable of handling 1 – 7 probes. Attachment to vessels is accomplished with external pipe threading. 3E fittings require the use of 3R rigid or 3W wire suspended electrodes.
