Optical Dissolved Oxygen Sensor Offers Expanded Communication Capabilities

GF Piping Systems has introduced the Signet 2610-41 optical dissolved oxygen sensor featuring expanded communication protocol capabilities. The 2610-41 sensor utilizes optical technology to measure dissolved oxygen with high reliability and accuracy in a wide variety of applications.

The new sensor model incorporates the Signet Sensor System Link (S3L) digital communication link that allows direct connection to the Signet 9900 SmartPro Transmitter Generation III as well as to the Signet 8900 Multi-Parameter Controller.

The transmitter supports the new sensor with a dedicated dissolved oxygen instrument that allows for selection of measurement type, ppm, percent saturation or partial pressure of oxygen. The transmitter also allows for setting of system specific parameters to increase the accuracy of the dissolved oxygen measurement.

The 2610-41 includes a built-in Modbus RS485 and 4 to 20 mA current loop outputs provide ease of interface to existing control systems. Operating capabilities feature a measurement range of 0 to 20 mg/L, 0 to 200 percent saturation and accuracies of ± 0.1 mg/L for 0 to 8 mg/L and ±0.2 mg/L for 8 to 20 mg/L. An optical sensor cap with built-in calibration eliminates the need for field calibration and has a one year lifetime compared to membrane life, which is typically three to six months. The sensor is CE and FCC approved and available with two week lead-time.

The Signet dissolved oxygen sensor is suitable for use in a wide range of applications including municipal and industrial wastewater treatment, drinking water reservoir monitoring, environmental water discharge monitoring and aquaculture and aquatic life support.
