Fiber Optic, Thermocouples & Resistance
Industrial & Aircraft Applications
Conax Buffalo Technologies’ Fiber Optic Temperature System revolutionizes temperature measurement in gas turbine engines. Conax’s new optical sensor system operates directly in the turbine inlet, withstanding temperatures and gas flow rates far beyond the capability of conventional sensor technology.
Thermocouples with termination assemblies
Conax Buffalo High Temperature Thermocouples are specifically designed for durability and reliability in high temperature applications to 4200°F (2315°C). Such applications generally involve oxidizing, reducing, inert gas or contamination atmospheres that challenge the life of the thermocouple.
EGC Thermocouples
Conax Buffalo Technologies has qualified a line of exhaust gas and wheel space thermocouples to retrofit various GE frame size gas turbine engines. These sensors are engineered and manufactured specifically to the latest revision of OEM specifications.Conax Buffalo Technologies exhaust gas sensors incorporate high reliability mineral insulated cable, with Type K wire and MgO insulation hermetically sealed in 316 Stainless Steel.
With Termination Assemblies
Conax Buffalo Technologies offers a complete line of dependable, ruggedized RTDs, ranging from thin film platinum sensors to wire wound sensor configurations available in platinum, nickel and copper. Conax can custom design RTD configurations to suit your specific needs, from trimmable RTDs, which provide added field installation flexibility, to fast response RTDs, for applications where response time is critical.
Body Assembly Parts
Quality Thermowells, Head Terminations & Wire Seal Terminations
Standard & Custom-Made
Conax Buffalo Technologies offers a full line of thermowells for applications from petrochemical to sanitary environments. Conax Buffalo Technologies thermowells are found in power plants, chemical plants, refrigeration and air conditioning systems, refineries, food service and pharmaceutical industries. From standard to custom designs, we can provide a thermowell to meet your requirements.
Head Assemblies
Conax Buffalo Technologies offers an extensive selection of standard and custom-engineered temperature sensor calibrations and configurations, sheath materials and terminal heads in various types, materials, and mounting styles to create the ideal assembly for your requirements. Every Conax sensor delivers rugged, reliable service with accurate, precision performance.
Wire Seal Termination Assembly
The type C is a lightweight head which provides a convenient and compact method of terminating thermocouple wires and connecting cold end leads. Screw posts, mounted in high purity alumina, securely fasten leadwires in position. The TG gland has an operational temperature range of –300°F to 1600°F (–185°C to +870°C) and pressure range up to 10,000 PSI @68°F (690 bar @ 20°C), dependent upon the installed sealant material type.
Temperature Transmitters
Quality Transmitters of various types
2-Wire transmitters for RTDs
The Conax Model HPT is a low cost, 2-wire, non-isolated temperature transmitter for RTD sensors, and is designed to fit in our popular T11 model terminal head.The HPT housing has a removable base allowing access to the electronics for the purpose of temperature range changes, which are easily accomplished with plug-in resistors
2-Wire Temperature Transmitter for RTDs or Thermocouples
The Conax Model HPTI is a low cost, 2-wire, non-isolated temperature transmitter for RTD sensors, and is designed to fit in our popular T11 model terminal head.The HPTI housing has a removable base allowing access to the electronics for the purpose of temperature range changes, which are easily accomplished with plug-in resistors
HART® Smart Isolated 2-Wire Transmitter for RTDs & Thermocouples
The Conax Model HST HART® Smart Isolated 2-Wire Transmitter features universal input capability in 3 variations to accept most of today’s process parameters: Thermocouples, RTDs, DcmV, Potentiometers, Resistance Sensors, DcmA, DCV, AC Amps, Frequency and Pulse. Fully software driven. All input parameters are programmable. An external hand-held programmer, an integral transmitter-mounted programmer or HART protocol hand-held enables on site calibration, and indication of process parameters.
DIN Rail-Mounted Transmitter for Any T/C
The Conax Model DRT2-T/C and DRT4-T/C are compact, DIN rail-mounted transmitters for any thermocouple type. The units provide an output which is linear with respect to the thermocouple sensor’s mV input. The units are powered by standard industrial loop powered supply and provide a 4-20mA current loop output on a 2-wire transmitter system (DRT2-T/C) or any standard current or voltage output on a 4-wire system (DRT4-T/C).
DIN Rail Mounted Transmitter for Any T/C
The Conax Model DRT2-RTD and DRT4-RTD are compact, DIN rail-mounted transmitters for 2, 3, and 4 wire RTD sensors. The output is linear with respect to the sensor’s temperature. The 4-wire input circuitry provides near perfect compensation for the effect of long leadwire resistance. They are powered by standard industrial loop power supply and provide a 4-20mA output on a 2-wire transmitter system (DRT2-RTD) or any standard current or voltage output on a 4-wire system (DRT4-RTD).
PC-Programmable 2-Wire Transmitter, DIN rail-mount for RTDs and thermocouples
All input types and range parameters are easily configurable with user-friendly technology. No power supply is required for programming. The PA-400 programming adapter and the graphic user interface software is PC-compatible.
PC Programmable DIN Rail Mount Transmitter for Thermistors
The Conax Model PDT-400 is a slim DIN rail-mount programmable 2 wire transmitter, featuring a state-of-the-art microprocessor-based design that enables full configuration with user-friendly configuration software.
PC Programmable Transmitter for RTDs and Thermocouples
All input types and range parameters are easily configurable with user-friendly technology. No power supply is required for programming.
Wall-Mount Temperature Sensor
Wall mount temperature sensors provide highly accurate measurement of room air temperature in industrial workspaces and commercial, industrial or apartment buildings. The RTD sensor is housed in an attractive enclosure that offers very stable readings. These units submit input to readouts and HVAC controls, and when combined with a data logging device, can provide a history for validation of room ambient temperatures.
