Product Description
GF 3-2751 pH/ORP Smart Sensor Electronics is a blind transmitter that processes analog signals from a pH or ORP electrode and transmits digital data via a three wire cable to a 9900 or 9950 GF transmitter or a GF 0486 Profibus Concentrator. The serial bus, GF Serial Sensor Link (S3 L) is the latest development in leading-edge technology from GF. The GF 2751 can also output the signal over a 4 to 20 mA current loop with a pre-set scale without the expense of local display. Preamplification is built-in reducing system costs while ensuring absolute signal integrity up to 305 m (1,000 ft).
The Smart Sensor Electronics self-configure for pH or ORP via automatic recognition of electrode type. The DryLoc electrode connector quickly forms a robust assembly with the sensor for submersible and in-line installations. The Smart Sensor Electronics offers broken glass and high impedance detection, remote calibration, storage of environmental extremes, and manufacturing electrode data. (see page 10 for details).
NEMA 4X Junction Boxes are integral parts of the in-line version and are available as accessories for the submersible version.
The optional EasyCal feature allows simple push-button calibration and includes an LED for visual feedback.
Product Information
Probe health monitoring, glass impedance and broken glass detection
Memory chip interface that allows for transferable calibration, runtime data, and manufacturing information
In-line integral mount version
Automatic temperature compensation
Auto configuration for pH or ORP operation
Optional EasyCal calibration aid with automatic pH buffer recognition for 4, 7 and 10 pH and ORP solutions: quinhydrone saturated pH 4 or 7 buffers and Light's Solution +469 mV
Patented DryLoc connector provides a quick and secure connection to the sensor
