• sig2250Sensor

    The Signet 2250 Hydrostatic Level Sensor for level and depth control has a one-piece injection molded PVDF body and ceramic diaphragm for superior compatibility in corrosive liquids. Utilising hydrostatic pressure the 2250 disregards false level signals from steam vapors, foam or any other debris on the liquid surface. Two pressure ranges allow for optimal resolution matched to your sensing needs. Solid state circuitry eliminates drift (no internal potentiometers). Built-in temperature compensation provides outstanding accuracy over wide temperature ranges. These sensors are available with a proprietary digital output (S3L), or 4 to 20 mA output. The extended cable and capillary tubing with the union connection and a customer supplied conduit, allow submersion in process vessels. Integral adapters (sold separately) may be used to create a compact assembly with field mount versions of the Signet 8250 Level transmitter.

    Advantages:

    • Level/depth measurement
    • 4 to 20 mA or digital (S3L) output
    • One-piece injection molded PVDF body
    • Flush ceramic diaphragm
    • Easy submersible installation
    • Choice of two pressure ranges
    • Standard union connection and extended cable and capillary tubing 10 m (32.8 ft)

  • The type 2260 is a rugged, high performance ultrasonic level measurement transmitter, having transducer and processing electronics and a display/programming unit incorporated in one single housing.
    All type 2260 Level Transmitters are using established high end pulse echo transducers, which provide narrow beam angles and reliable measurement ranges up to a distance of 15 meters.
    For small, stand alone tanks the transmitter provides a simple 2-wire 4 to 20 mA output, with additional power relay contacts. It can be programmed using push buttons and the large, graphic display. For large and/or multiple tank applications versions with HART interface are recommended, communicating directly with a panel mount controller or PLC. The HART protocol can easily be used for programming these versions.

    Applications
    • River water
    • Seawater
    • Potable water
    • Demineralized water
    • Treated water

  • The type 2270 is a rugged, high performance ultrasonic level measurement sensor, having transducer and processing electronics incorporated in one single housing. It provides all the sophisticated echo detection features of the well accepted 2260 Ultrasonic Level Transmitters.
    For single and multiple tank applications 2-wire sensors are recommended using either HART protocol or 4 to 20 mA for the direct communication with a panel mount controller or a PLC.
    Either for liquid level measurement in sumps or tanks, for tank contents measurement, or open channel flow measurement, the 2270 Level Sensors provide the answer. Sensing ranges up to 6m are available. PP and PVDF sensor bodies provide best chemical resistance in applications where concentrated chemical shall be detected.

    Applications
    • River water
    • Seawater
    • Potable water
    • Demineralized water
    • Treated water

    Discontinued - No Longer Available        (See 9900 Transmitter)  

    Signet 8250 Level Transmitters are compatible with the Signet 2250 Level sensor and 2450 Pressure Sensor. The instrument is available in field and panel mount configurations, single or dual-channel input and equipped with one 4 to 20 mA output, fully scaleable and reversible for each input channel. The unit also features two relays, plus the ability to support two additional externally mounted relays (for a total of four). Relay operation is selectable for High, Low, Window or Off, and includes fully adjustable hysteresis and trigger time delay. The unit also has the ability to accept other level sensors with 4 to 20 mA output via the Signet 8058 Signal Converter. Automatic level-to-volume conversion allows display and control of tank volume and/or level in units such as gallons, kilograms, feet or meters. Simply enter the dimensions of your tank or vessel, and the instrument will calculate volume from the level measurement.
