• Data Sheet - 8250 Level Transmitters (pdf, 0.3 MB)

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 operations is selectable for High, Low, Window or Off, and includes fully adjustble 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 level and/or volume 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.

Fields of Application:

• Continuous level and/or volume monitoring
• Local or remote display
• Fill start/stop control

2250 Hydrostatic Level Sensor

Data Sheet - 2250 Submersible Hydrostatic Pressure (pdf, 0.3 MB)

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.

Fields of Application:

• Inventory Management
• Storage Tank Monitoring
• Neutralisation Tanks
• Plating Lines
• Waste Sumps
• Clarifiers
• Overflow Protection

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)

Standards:

• CE
