Digital Switch controls water temperature.
Series TSWB Digital Temperature Switch has high and low set point for controlling water temperature; low set point can either be manually or automatically reset. Control also has conductivity level probe input, which supplies 12 Vac to probe to check for low water condition. Unit includes 3 relay outputs which can be assigned in field to high water temperature set point, low water temperature set...

Conductivity Level Probes resist heat and corrosion.
Mounted in any orientation in tank, tee fitting, or any compatible threaded port, Series CLP determines presence of conductive liquid at set level by sensing conductivity. Probes allow for measurement of conductivity between probe fitting and end, which is isolated by ceramic insulator, or between ends of 2 probes. Offered with -½ in. NPT process connection, probes feature solid stainless steel...

Leak Detection Relays offer 3 different sensitivities.
Single-channel Series SLD monitors shaft seal of submersible pump to detect leak before pump failure. Leak is detected by sensing status of float or conductivity switch installed in seal cavity. When resistance drops below set sensitivity, output relay energizes and LED indicator illuminates. Utilizing 120 Vac control voltage, relays offer sensitivities of 470 W fixed, 470 to 10 kW adjustable,...

Relay detects leaks and over-temperature conditions.
Series LDT monitors shaft seal and stator temp of submersible pump to help prevent failure. When leak is detected, output relay energizes, and LED indicator illuminates. Relay automatically resets when seal failure condition clears. NC temperature switch, mounted on stator, detects over-temperature, and bi-stable relay retains its position during power loss and latches on until remote reset...

Electro-Pneumatic Transducers regulate branch pressure.
Incorporating 2 valves, in-barb filter, 30 psi analog gauge, anodized aluminum manifold, and brass barbed fittings, Series EPTA converts analog input signal to linearly proportionate pneumatic output by modulating control valves to regulate branch pressure. Standard models maintain branch pressure on power loss, while Fail-Safe models will drop branch pressure to 0 psi. Immune to mounting...

Spring Check Valves prevent flow reversal in piping systems.
Operating without any adjustments or settings, Series SCV is suited for use where backflow could potentially cause damage to pumps, filters, or process equipment. Line pressure moves plastic cone off elastomer seat, opening valve. When inlet flow stops, spring moves cone back onto seat to stop flow. True union design facilitates removal from piping system without breaking down piping connections....

Capacitive Sensor offers 10 mm sensing distance.
Featuring thin profile, Series NCS-10 offers sensing distance of 10 mm non-flush mounted and provides 3-wire dc output with selectable NO or NC switching and NPN alarm. Switching points can be altered by means of push-button teach-in function. Designed for front, pipe, or plane mounting, sensor can detect metallic as well as non-metallic objects, but is mainly used in plastics, chemical, wood,...
