  • Ashcroft DM61 Digital Display

    Item Type Power Type Input Signal Type Measurement Display Type
    Industrial VAC Direct, VDC Direct mA, Modbus, Voltage Any

    Ashcroft® type DM61 digital panel meters are ideal for fulfilling application requirements where monitoring and/or data-logging is necessary. Incorporating user-friendly functions, they allow for quick set up and programming. The dual-line indication offers a distinct benefit for level measurement and the large panel display supplies high accuracy and precision due to an internal 24-bit A/D converter. Common applications include tank level monitoring & control, pump & flow control, and remote pressure indication.

  • Gems 54800 Dual Channel Zener Barrier

    Manufacturer Series
    Gems 54800 Dual Channel

    Gems® type 54800 dual channel zener barriers provide intrinsic safety with solid-state reliability. Since no explosion proof enclosures are needed for sensor wiring, these units further provide economical installation. With encapsulated construction, they are impervious to dust and moisture. They are used with instrumentation that produces an output (signal conditioners) and requires two barriers, one for each floating lead. Any non-voltage producing sensor or switch is rendered intrinsically safe for hazardous locations when properly connected to the output of these zener barriers.

  • Gems 65800 Single Channel Zener Barrier

    Manufacturer Series
    Gems 65800 Single Channel

    Gems® type 65800 single channel zener barriers provide intrinsic safety with solid-state reliability. Their exceptionally compact design saves space and simplifies installation, especially in multiples on a common mounting plate. With encapsulated construction, they are impervious to dust and moisture. They provide great economy as well since no explosion proof enclosures are needed for sensor wiring. Single screw mounting is standard, but units can be supplied with an optional clip for rail mounting. Any non-voltage producing sensor or switch is rendered intrinsically safe for hazardous locations when properly connected to the output of these zener barriers.

  • Gems Non-Intrinsically Safe SAFE-PAK Relay

    Manufacturer Series
    Gems Non-Intrinsically Safe SAFE-PAK

    Gems® non-intrinsically safe relays perform the functions of electro-mechanical relays, with the added reliability and advantages inherent in solid-state. Compact, totally encapsulated, and impervious to shock or vibration, these units mount anywhere, even directly on working machinery. LOAD-PAKS are integrated, solid-state switches that amplify current handling capabilities of sensors for controlling high power loads. SPDT-PAKS enable one low current sensor to control two independent loads up to 5 amps each. FLIP-PAKS provide low current, start-stop or on-off switching for industrial motor, liquid level, and other control systems.

  • Gems Programmable SAFE-PAK Relay

    Manufacturer Series
    Gems Programmable SAFE-PAK

    Gems® programmable SAFE-PAK relays are designed for use with switches or sensors monitoring flow, pressure, level, etc. They render non-voltage producing sensors intrinsically safe for operation in potentially hazardous areas and feature streamlined housing suited for group-mounting on a common earth-grounded plate for multiple installation. Operations such as normally open, normally closed, or latching are programmed into these versatile units by the user during installation.

  • Gems SAFE-PAK Relay

    Manufacturer Series
    Gems Gems SAFE-PAK

    Gems® SAFE-PAK relays make costly explosion proof enclosures with their special mounting requirements unnecessary. No purging is required. Sensor closures up to 1000 ohms resistance control resistive loads to 5A at 120 VAC.

  • Harwil CF-112 Chemical Feed Pump Controller

    Manufacturer Series
    Harwil CF-112

    Harwil® type CF-112 chemical feed pump controllers are stand alone interface modules that automatically actuate a chemical feed pump when primary bulk fluid begins to flow. These modules can be used in isolated stand alone systems or as part of large complex systems. Typical uses are for metering and/or adding chemicals in both continuous and batch fluid systems such as: well water, drinking water, waste fluid processing, cooling tower pH/orp control, metal plating make up solutions, and boiler treatment additives.

  • Harwil CF-12/1G Chemical Feed Pump Controller

    Manufacturer Series
    Harwil CF-12/1G

    Harwil® type CF-12/1G one gang chemical feed pump controllers are stand alone interface modules that automatically actuate a chemical feed pump when primary bulk fluid begins to flow. These modules can be used in isolated stand alone systems or as part of large complex systems. Typical uses are for metering and/or adding chemicals in both continuous and batch fluid systems such as: well water, drinking water, waste fluid processing, cooling tower pH/orp control, metal plating make up solutions, and boiler treatment additives.

  • Harwil CF-12/2G Chemical Feed Pump Controller

    Manufacturer Series
    Harwil CF-12/2G

    Harwil® type CF-12/2G two gang chemical feed pump controllers are stand alone interface modules that automatically actuate a chemical feed pump when primary bulk fluid begins to flow. These modules can be used in isolated stand alone systems or as part of large complex systems. Typical uses are for metering and/or adding chemicals in both continuous and batch fluid systems such as: well water, drinking water, waste fluid processing, cooling tower pH/orp control, metal plating make up solutions, and boiler treatment additives.

  • Harwil CF-8/1G Chemical Feed Pump Controller

    Manufacturer Series
    Harwil CF-8/1G

    Harwil® type CF-8/1G one gang chemical feed pump controllers are stand alone interface modules that automatically actuate a chemical feed pump when primary bulk fluid begins to flow. These modules can be used in isolated stand alone systems or as part of large complex systems. Typical uses are for monitoring fluid flow in air conditioning systems, cooling in data centers, chillers, fluid blending systems, natural gas, industrial refrigeration systems, pools & spas, scrubbers, and water treatment systems.
