Signet 8900 Multi-Parameter Controller External 4-relay module

The Signet 515 Rotor-X paddlewheel flow sensors are offered in a variety of materials for a range of pipe sizes. Paddle wheel flow sensor material include Polyprpylene and PVDF. The 515 Rotor-X is highly versatile and usable with many liquid process flow solutions. 515 Rotor-X paddle wheel flow sensors can be installed using Signet’s comprehensive line of custom flow fittings.

525 Metalex Flow Sensor offers the added strength of an all stainless steel construction with insertion paddlewheel technology. The result is a highly reliable sensor resistant to extreme pressures and temperatures. The Tungsten Carbide shaft with Fluoroloy B® bearing provide an increased length between maintenance.

Engineered specifically for small diameter applications, the Signet 2100 Turbine Flow Sensor provides accurate readings in two flow ranges; 0.3 to 3.8 lpm and 3 to 38 lpm (0.1 to 1 gpm and 0.8 to 10 gpm). The injection-molded PVDF body and ceramic bearings provide excellent chemical compatibility and long service in dosing and batching applications. Union piping and tubing connections along with removable NEMA 4X electronics allow for easy assembly and field replaceability. The Signet 2100 can be used with DN8 (¼ in.), DN10 (? in.), or DN15 (½ in.) tubing, or DN15 (½ in.) piping for simple installation. End connections are available in PVDF for hose barbs, fusion socket or IR/butt fusion, and in PVC for socket or NPT thread.
Typical applications:

• Chemical Addition
• Textile dyeing
• High-purity Chemical Dispensing
• Water Addition
• Fertigation
• Dosing
• Pump Protection
• Not suitable for gases

The 2350 Temperature Sensor has aPVDF body to maintain purity and outlast metal sensors in corrosive liquids eliminating. Standard 3/4” NPT thread allows simple installation in any piping system. Threaded both ends allow for submersion in process vessels or for in-line applications with attachment of conduit. Digital signal allows for wiring distances betweensensor and Signet 3-8350 Temperature Transmitter of up to 200 ft.

The Signet 2507 Mini Flow Sensor contains a free-running rotor that is driven by the fluid flow.Magnets built into the rotor trigger an electronic switch in the top of the sensor creating a square-wave output. Both opaque and transparent fluids can be measured from 0.2 to 20.0 centistokes.

Simple to install with time-honored reliable performance, Signet 2536 Rotor-X Paddlewheel Flow Sensors are highly repeatable, rugged sensors that offer exceptional value with little or no maintenance. The Model 2536 has a process-ready open collector signal with a wide dynamic flow range of 0.1 to 6 m/s (0.3 to 20 ft/s). The sensor measures liquid flow rates in full pipes and can be used in low pressure systems.
The Signet 2536 Rotor-X Paddlewheel Flow Sensors are offered in a variety of materials for a wide range of pipe sizes and insertion configurations. The many material choices, including PP and PVDF, make this model highly versatile and chemically-compatible with many liquid process solutions. Sensors can be installed in DN15 to DN900 (½ to 36 in.) pipes using Signet's comprehensive line of custom fittings. These custom fittings, which include tees, saddles, and weldolets, seat the sensor to the proper insertion depth into the process flow. The sensors are also offered in configurations for wet-tap installation requirements.
Typical applications:

• Pure Water Production
• Filtration Systems
• Chemical Production
• Liquid Delivery Systems
• Pump Protection
• Scrubber Systems
• Water Monitoring
• Not suitable for gases

The Signet i-Go 8058 Signal Converter accepts any 4 to 20 mA signal and converts it into the Signet digital format which is the serial data format used by the Signet 8350, 8450, 8900 and 9900 instruments. When used with level, temperature and pressure transmitters, the 8058 is configured at the factory to the user's specifications if connecting an 8058-2 to a 9900 Transmitter, Use Channel 1 only.

The Signet 2850 Conductivity/Resistivity Sensor Electronics are available in various configurations for maximum installation flexibility. The universal mount version is for pipe, wall, or tank mounting and enables single or dual (digital versions only) inputs using any standard Signet conductivity / resistivity sensor. The threaded j-box version can be used with these same Signet sensors for submersible sensor mounting. It is also available as a combined integral system configuration for in-line mounting and includes a conductivity electrode in a choice of 0.01, 0.1, 1.0, or 10.0 cm-1 cell constants. The 2850 is ideal for applications with a conductivity range of 0.055 to 200,000 ?S or a resistivity range of 18.2 M? to 10 k?. All 2850 units are available with a choice of two outputs: digital (S3 L) or 4 to 20 mA. The digital (S3 L) output version allows for up to six sensor inputs directly into the Signet 8900 Multi- Parameter Controller. The two-wire 4 to 20 mA output is available with eight 4 to 20 mA output ranges for each electrode cell constant. Additionally, each range can be inverted and are field selectable by the user. All 2850 units are built with NEMA 4X/IP 65 enclosures which allow wiring connections with long cable runs of up to 1,000 feet (305 m). EasyCal is a standard feature that automatically recognizes conductivity test solution values for simple field calibration. A calibration tool is available for validation of the sensor electronics according to USP requirements.
Typical applications:

• Water Treatment & Water Quality Monitoring
• Reverse Osmosis
• Deionization
• Demineralizer, Regeneration & Rinse
• Scrubber, Cooling tower and Boiler Protection
• Aquatic Animal Life Support Systems
