Signet Instruments

AES offers the full line of GF Signet Sensors and Instruments, the most common models are listed below, but additional models and configurations are also available upon request.

• Multiparameter Controller 8900
• Flow
• pH/ORP
• Conductivity/Resistivity

Multi-parameter Controller 8900:

It allows the user to combine parameters in one single instrument; it can be customized with inputs, relays, outputs, power supply, etc. It is easy to install and to configure.

Flow

• 515 Rotor-X Paddlewheel Flow Sensors: They are available in a variety of materials and for a wide variety of pipe sizes. It has a dynamic flow range of 0.3 to 6 m/s (1 to 20 ft/s).
• 8150 Battery Powered Flow Totaliser: is compatible with the Signet 515 and 525 flow sensors. It indicates flow rate and totalised flow volume simultaneously.
• 5500 ProPoint® Flow Monitor: This flow monitor has a scaleable 4 to 20 mA output and two relays programmable for high, low, and pulse operation. It indicates flow rate with the analog dial; it also has a backlit LCD for calibration, set-up and totalized flow volumes.
• 8150 Battery Powered Flow Totaliser: is compatible with the Signet 515 and 525 flow sensors. It indicates flow rate and totalized flow volume simultaneously on its large digital display.
• 8550 ProcessPro® Flow Transmitter: It is compatible with all signet sensors, it converts their signal into a 4 to 20 mA signal and it has dual input and output capability. It can be installed with the integral pipe mount kit or it can be installed in a panel.

pH – ORP

• 2724-2726 pH-ORP Electrodes: These sensors are available as flat pH, bulb pH, or flat ORP sensing elements to be used in any application. The sensors have ¾” NPT or ISO 7-1 R¾ threads for installation into standard tees and they can also be mounted directly into Signet standard fittings.
• 2774-2777 pH/ORP Electrodes: These sensors have been designed to be used with the 2750 and 2760 preamplifiers, sensor electronics and connectors. The sensing elements are available in either flat or bulb styles.
• 2714-2717 pH/ORP Electrodes: These elements are constructed of rugged CPVC and have a very simple twist-lock design which enables de connections in one easy motion. It includes a integral temperature sensor in the pH electrode and the I.D. circuit on the ORP electrode
• 2750 pH/ORP Sensor Electronics: This sensor electronic has a preamplified signal and two different outputs a 4 to 20 mA loop or a digital S3L. It is compatible with the 8900 Multiparameter controller. It configures itself for pH or ORP operation and can be used in submersible or in-line installations.
• 2760 pH-ORP Preamplifiers and Connectors: This preamplifier allows the use of any DryLoc® pH/ORP electrode to work with the ProcessPro® and ProPoint® pH and ORP instruments. Ut can also be used as a connector for other instruments that do not need a preamplified signal.

Conductivity – Resistivity

• 2819-2823 Conductivity-Resistivity Electrodes: These sensors are easy to install and are very accurate in a broad range. The standard sensor is built of 316 SS or Titanium but other materials are available.
• 2850 Conductivity-Resistivity Sensor Electronics and Integral System: It is available in a universal mount version which allows installation on pipes, walls or tanks. The threaded j-box version can be used with all the sensors for submersible mounting; it is also available as integral mounting system for in-line mounting which includes an electrode with a choice of 5 five different constants to fit different applications.
• 5800CR ProPoint® Conductivity-Resistivity Monitor: It has an analogue display allows a quick at-a glance view of the measurement and a digital display for set-up and more detailed precise information.
• 8850 ProcessPro® Conductivity-Resistivity Transmitter: This transmitter works in a broad range of applications and is very easy to install and use. It is available in three different versions; the traditional two-wire loop, a current loop plus two dry contact relays and one with a two-wire current loop, one sensor input signal and two current loop outputs.
