GF Signet 2650 Amperometric Electronics - Manual

2. Installation - Tee Fitting
The Signet 2650 Amperometric Electronics provide the polarization voltage and signal conditioning required by all Signet
Amperometric Sensors. Sophisticated circuitry makes system setup and verifi cation easy.
Features:
•
Passes data stored in sensor memory, such as factory calibration data, service time, range and more.
• Signet's patented DryLoc ® connector provides quick assembly and a secure connection. Gold-plated contacts and an O-ring seal
ensure a waterproof and reliable interconnect to the sensor.
• Separate drive electronics from sensor make for easy sensor replacement without running new cable.
• DryLoc connectivity allows easy sensor removal for calibration.

CHEMICAL COMPATIBILITY WARNING
The retaining nuts of Amperometric sensors are not designed for prolonged contact with aggressive substances. Strong
acids, caustic substances and solvents or their vapor may lead to failure of the retaining nut, ejection of the sensor and
loss of the process fl uid with possibly serious consequences, such as damage to equipment and serious personal injury.
Retaining nuts that may have been in contact with such substances, e.g. due to leakage or spilling, must be replaced.
