Resistivity, Conductivity Electronics | 2850

Resistivity or Conductivity Electronics Overview

The GF Signet 2850 Conductivity/Resistivity Sensor Electronics are available in various configurations for maximum installation flexibility. The threaded j-box version can be used with these same GF Signet sensors for submersible sensor mounting. Universal mount version used for pipe, wall, or tank mounting and enables single or dual (digital output only) inputs using any standard GF Signet conductivity / resistivity sensor. 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 100 MΩ to 10 kΩ. Each range can be inverted and are field selectable.

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

The 8900 Multi-Parameter Controller allows for up to six sensor inputs directly into the Georg Fischer 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).

Magmeter Flow Sensor | 2551

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.
