With its ability to read accurately when other non-contacting or invasive methods fail, the guided level transmitter type 2291 using GWR (guided wave radar) is the solution to your level needs.
The radar signal is sent down the probe assembly eliminating the interferences caused by low dielectric liquids, heavy fuming, slightly conductive foams, internal tank obstructions, etc. By focusing its energy along the probe, the type 2291 can be installed in tanks with limited space.
The type 2291 is also less sensitive to turbulence that would normally upset the readings in ultrasonic and unguided radar technologies.

Applications:
• General – Challenging tank applications where other non-contacting principles fail e.g. ultrasonic or unguided radar
• Chemical Process Industry – Storage of solvents, chlorine or ammonia, level detection in reaction vessels or buffer tanks
• Water Treatment – Pumping stations, sludge handling, drain level monitoring, drinking water conditioning vessels

8058 Signal Converter

The Signet i-Go 8058 Signal Converter accepts any 4 to 20 mA signal and converts it into the Signet digital (S3L) format, the serial data format used by the Signet 8250, 8350, 8450 and 8900 instruments. When used with the 8900 Multi-Parameter Controller, the measurement type and operating range are defined in the 8900 setup menu.

When used with level, temperature and pressure transmitters, the 8058 is configured at the factory to the user's specifications. The wire-mount single-channel version is easily mounted anywhere in the interconnecting wiring between the sensor and the instrument.

The DIN rail mounted dual-channel version can convert one or two separate 4 to 20 mA inputs into a digital (S3L) output.

The 9900 Transmitter

Fot at-a-glance visibility, the 9900 Transmitter features a large auto-sensing backlit display, "dial-type" bar graph and relay and warning LEDs. The intuitive menu system is consistent with processPro and ProPoint transmitters, assuring you of a quicker and easier installation. The optional Relay, Direct Conducttivity/Resistivity, H COMM and Batch plug-in modules offers ease of use. The PC COMM configuration tool allows you to easely set-up, review, save and load all modifiable parameters. The unit can be used with default valves for quick and easy programming or can be customised with labelling, ajustable minimum and maximum dial settings, and unit and decimal measurement choices. The versatile device also allows third-party 4 to 20 mA signals to be used as an input (optional 8058 module required).

The 9900 Transmitter, a member of Signet's line of SmartPro  instruments, provides a single-channel interface for all Flow, pH/ORP, Conductivity/Resistivity, Salinity, Pressure, Temperature, Level, Dissolved Oxygen, Turbidity, Batch and other applications.

The 9900 is available in Panel Mount. And  runs on 10.8 to 35.2 VDC power (24 VDC nominal), and can power certain sensors on loop power.

Two dry-contact relays

In addition to the standard programmable Open Collector output in the base unit, the Panel Mount version of the 9900 has a slot for an optional Relay Module, which adds two programmable dry-contact relays. The Open Collector output in the base unit uses the Relay.

Dry-contact relays are electromechanical switches with a moving contact armature.

They are suitable for many general-purpose applications, AC or DC, including AC loads up to 250 V. Install RC Filter Kits, 3-8050.396, on relays used to switch motor or inductive loads.

 ● Two (2) SPDT dry-contact relay (DCR) inputs

 ● User programmable

 ● 250 V, 5 A maximum resistive loading (AC).

 ● Can switch line voltage (typically 120 to 240 VAC)

 ● Can switch DC voltage (< 30 VDC @ 5A)

 4 to 20 mA Output Module adds an additional 4 to 20 mA loop output to a Signet 9900 Transmitter

 ● 4 to 20 mA Output Module can be powered using Loop Power or DC Power in the 9900 base unit.

 ● Independent settings for the loop currents of the Output Module and 9900 base unit (Error, Loop Adjustments, etc.).
