Signet Multi-Parameter Controller
The Signet 8900 Multi-Parameter Controller takes the concept of modularity to the extreme. Each 8900 is field commissioned with the users specified combination of inputs, outputs, and relays using simple-to-install modular boards into the base unit. To assemble a controller, there is a choice of two base units offered with a choice of back-lit LCD or vacuum fluorescent display. Then, continue building with a selection of plug-in modules for either two, four, or six input channels which accepts any of the Signet sensors listed below, and/or other manufacturer's sensors via a 4 to 20mA signal converter (Signet Model 8058). To complete your unit, choose a power module with universal AC line voltage or 12 to 24 VDC.
Measures Flow, pH, ORP, Conductivity, Pressure, Level and Temperature
1/4 DIN enclosure
Up to 4 analog outputs
Up to 8 relays
12 to 24 VDC or 85 to 264 VAC Power
Digital Communication for improved noise tolerance, extended cable lengths, and easy wiring
Accepts 4 to 20mA output devices when used with 8058 signal converter
Signet 2750 and 2760 DryLoc® pH/ORP Sensors The Signet 2750 and 2760 pH/ORP Sensor Electronics and Preamplifiers, featuring DryLoc® connectors, provide a variety of functions to suit various requirements. The 2760 is a preamplifier that allows any DryLoc® pH/ORP electrode to work with most Signet instruments. It is also sold as a simple connector for use with other manufacturers' instruments that do not require a preamplified signal. The 2750 comes with the same pre-amplified signal as the 2760, but features two different outputs: a two-wire 4 to 20 mA loop output, or a digital (S3L) output which allows for longer cable lengths and is compatible with the Signet 8900 Multi- In-line 2750 DryLoc® Electrodes sold separately. Parameter Controller. The 2750 devices self-configure for pH or ORP operation via automatic recognition of the electrode type. The optional EasyCal feature allows simple push-button calibration and includes an LED indicator for visual feedback. The DryLoc® electrode connector found on both models quickly forms a robust assembly for submersible and in-line installations. NEMA 4X junction enclosures are integral parts of the 2750 in-line version and are also available as accessories for both Models 2750 (submersible version) and 2760.
Signet 2754-2757 pH and ORP Electrodes The Signet 2754-2757 pH and ORP Electrodes feature a unique foul-proof DryLoc® connector with gold-plated contacts designed specifically for use with the Signet 2750 and 2760 Sensor Electronics and preamplifiers. These dependable and highly responsive electrodes feature a large reference chamber volume and intelligent positioning of internal elements that combine to extend the service life. The electrodes are offered with either flat or bulb sensing elements. The flat versions allow sediment and particles to sweep past the measurement surface, minimizing the risks of abrasion, breakage and coating. The bulb versions can be used for general purpose applications and are also offered with a glass or plastic body for use with the 3719 Wet-Tap assembly. The choice of a PT-1000 or 3K? temperature sensor allows compatibility into all Signet pH/ORP instruments. The 2754-2757 electrodes are the flagship sensors of the Signet pH/ORP product line. They are all-purpose sensors ideal for a wide range of universal applications.
