Overview of Conductivity Sensor 2850

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, 1.0,10.0 or 20.0 cm-1 cell constants. The 2850 is ideal for applications with a conductivity range of 0.055 to 400,000 μS or a resistivity range of 18.2 MΩ to 10 kΩ.

All 2850 units are available with a digital (S3L) output, or a single 4 to 20 mA. The digital (S3L) output version can be paired with the 9900 or 9950 Transmitter to extend the distance between the measuring points to 120 m (400 ft).

The 8900 Multi-Parameter Controller allows for up to six 2850 (S3L) output conductivity sensors to be used with the Signet 8900 Multi-Parameter Controller. All 2850 units are built with NEMA 4X/IP65 enclosures which allow output wiring connections with long cable runs of up to 305 m (1,000 ft).

The two-wire 4 to 20mA output version is available with eight 4 to 20 mA output ranges for each electrode cell constant. Each range can be inverted and is ﬁeld selectable.

EasyCal is a standard feature that automatically recognizes conductivity test solution values for simple ﬁeld calibration. A certiﬁcation tool is available for validation of the sensor electronics according to USP requirements.

Magmeter Flow Sensor | 2551
Price range: R32,897.00 through R89,766.00

Magmeter Flow Sensor - Overview

This insertion magnetic flow sensor features no moving parts. It is available in corrosion-resistant materials to provide long-term reliability with minimal maintenance costs. Material options include PP with stainless steel, PVDF with stainless steel, PVDF with Hastelloy-C, or PVDF with Titanium. These versatile, simple-to-install sensors deliver accurate flow measurements for a wide range of pipe sizes ranging from DN15 to DN900 (½ to 36 inches), making them suitable for various applications. These Magmeters offer frequency/digital (S3L) or 4 to 20 mA output options. Both are available on the blind and display versions. The frequency or digital (S3L) sensor output can be used with Georg Fischer's extensive line of flow instruments while the 4 to 20 mA output can be used for direct input to PLCs, chart recorders, etc. Both the 4 to 20 mA output and the digital (S3L) sensor interface are available for long-distance signal transmission. An additional benefit is the empty pipe detection which features a zero flow output when the sensors are not completely wetted. Also, the frequency output is bi-directional and can be set using the 4 to 20 mA output, using the display, or the 3-0250 USB to Digital (S3L) set-up tool. The display version is available with relays and features permanent and re-settable total values which can be seen on the display. The display contains multi-language options such as English, Spanish, German, French, Italian and Portuguese.

Water Jet Suction Pump Valve | GF P20

Water Jet Suction Pump Valve - Overview

The water jet suction pump valve can be used where the liquid is under pressure and is present as a propellant. It is used for transporting and mixing liquids. The water jet suction pump valve is self-priming and has no mechanically moving parts. The basic principle of the water jet suction pump is that the propellant liquid passes through a nozzle and draws in with it the liquid or gaseous medium from the suction line, increasing its velocity. The result is that the propellant and the medium are sucked in and mixed together. Suitable for use in aquariums, the chemical process industry, industrial water treatment, and swimming pools.

Water Jet Suction Pump Valve - Features
- No external energy required for operation
- Ideal for mixing, dosing and transporting liquids
- No mechanically moving parts
- Self-priming

Free Chlorine Sensor | Chlori::lyser

Free Chlorine Sensor - Overview
The chlori::lyser is a revolutionary sensor for monitoring free chlorine or total chlorine. Its internal buffer electrolyte allows pH-independent measurement between pH 4 to 9+, and its 3-electrode system provides extremely stable readings. These sensors were developed for use in drinking water, pool water and different types of water treatment. The usage in wastewater is possible but has to be evaluated for the specific application. These sensors have only a low dependence on fluctuations of flow. However, a constant flow of the measuring medium is recommended. High precision is ensured even at high fluctuations of pH, temperature and flow. chlori::lyser™ monitors free chlorine (Cl2 + HOCl + OCl-) or total chlorine (free chlorine + combined chlorine)

Free Chlorine Sensor - Features
