2850-63: Sensor Electronics

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 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.

Digital (S3L) interface or two-wire  4 to 20 mA output. For use with ALL Signet conductivity electrodes.

8900: Input/Output Accessory

One I/O module is required to build a functional 8900. I/O modules are offered for 4 or 6 sensor inputs with or without two mA or voltage outputs.

Output modules are optional when building an 8900. This module can be used in addition to other outputs that are available in the I/O modules. Active current is powered by the 8900. Passive outputs require an external 12 to 24 VDC power supply.

8900: Relay Accessory

The 8059 External Relay Modules supplement the output capabilities of certain host instruments such as the 8900 Multi-Parameter Controller. AC-powered versions accept universal line voltage, and also provide 24 VDC output that can be used to power the host instrument or other device(s).

- Relay Outputs: 2 or 4 external contact relays. SPDT 250VAC/30VDC/5A

- Compatible Instruments: 8900 (S3L Instruments only)
