The Signet 2751 pH/ORP Smart Sensor Electronics featuring the DryLoc® connector, is the solution for fieldfree calibration, out of range glass impedance and broken glass detection, alerting the operator to probe failure or maintenance needs.
The 2751 features two different outputs: a two-wire 4 to 20 mA loop output with optional EasyCal function or a digital (S3L) output which allows for longer cable lengths and is compatible with all Signet 8900, 9900 and 9950* instruments or in blind, 4 to 20 mA.
The Smart Sensor Electronics will allow for calibration of electrodes in a laboratory setting and installation of precalibrated probes in the field, reducing system downtime. Memory chip enabled electrodes will store operational
data such as minimum and maximum pH/mV readings, runtime, minimum and maximum temperature (pH only), for troubleshooting and operational evaluation. To take full advantage of all features and benefits of the 2751, use with Signet 9900 (Generation IV or later), 9950 Transmitter or 0486 Profibus Concentrator.
The 2751 self-configures 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 2751 submersible Smart Sensor Electronic can also be used in-line when used with the 3/4” or 1” threaded sensors including the 272X, 273X, 275X, 276X and 277X series of electrodes. The 2751 in-line sensor electronics can be used with Signet fittings up to DN100 (4 in.) and Wet-Tap assemblies.
