GF Signet 9950 Six-Channel Transmitter

Connect up to 6 sensors with a daisy chain connection to the single transmitter

The 9950 boasts an array of standard features and options, enabling it to operate with increased flexibility compared to earlier GF instruments. Its utilization of a cutting-edge dot matrix display ensures effortless viewing and user-friendly menus. This, coupled with its capacity for both AC and DC power, as well as its compatibility with frequency, digital (S3L), and binary (switch) inputs, in addition to housing an onboard clock and calendar, opens the door to numerous novel application possibilities. Harrington carries an extensive selection of process instrumentation and control devices meticulously crafted to deliver precise and dependable monitoring and control solutions across diverse industrial processes.

State-of-the-Art Features

Compact yet powerful, the 9950 Six-Channel Transmitter offers two, four, or six channels with two passive 4 to 20 mA current loop outputs and an optional Modbus module. ​ Independent six-channel multi-parameter, flow, pH, ORP, conductivity, resistivity, pressure, temperature, level, volume, salinity, dissolved oxygen and other (4 to 20 mA).

Advanced Capabilities

With onboard clock/calendar, derived functions, advanced relay operation and Boolean logic you have seemingly countless configurations to meet your process control needs. 

Streamlined Operation

Now with two, four and six-channel options, the 9950 can easily replace multiple transmitters in a system while offering advanced functionality.

Simplified Automation

Automate processes with math and logic-controlled relays.

With its six-channel capability, users can connect up to Six (S3L) sensors, or five (S3L) and one frequency, or four (S3L) and two frequencies, in addition to four binary inputs. Additional versatility is provided with its capability for multi-parameters through the support of the complete line of GF flow and analytical sensors, as well as other devices with a 4-20 mA current loop output when using the GF iGo module.

Extensive Compatibility

  • With the automatic recognition of GF Piping Systems sensors, operating your application from a single point is seamless.
  • Compatible with the full GF Piping Systems portfolio of flow, pH/ORP, conductivity, resistivity, pressure, temperature and level sensors.
  • Additionally, when adding GF Piping System valves and actuators, the 9950 Six-Channel Transmitter becomes a powerful solution.

The base models are equipped standard with two analog 4-20 mA loop outputs that can be expanded up to six with optional dual 4-20 mA modules. The analog outputs can not only be spanned for primary and secondary sensor signals, but also for the differential of two like sensors such as delta temperature, or the very important delta pressure across filters; these analog outputs can also be used to proportionally pace metering pumps, drive recorders, PLCs, SCADA, DCS. There are endless other input and output capabilities.
