The REOTEMP Model W Explosion Proof, Field Mounted, HART Temperature Transmitter
Process control instrumentation monitors and controls a process to maintain proper functioning standards and keep it within a proper functioning and safe operating range. Process variables are the parameters or quantities maintained to keep the process within desired and acceptable limits. Instrumentation systems compare process variables to a desired setpoint and then produce offsetting and corrective control outputs.
Typical process variables are level, flow, temperature, density, pH (acidity or alkalinity), mass, and conductivity.
Temperature is a measurement of how hot or cold something is, whether it's an object or a process medium. The temperature setpoint is the process variable's target value for optimum control, quality, and safety. In a process where the temperature stays within plus or minus 1 degree Celsius of 100℃, the setpoint is 100.
Temperature transmitters are instruments that convert a weak thermocouple or RTD signal to a robust analog (4-20mA or HART) or digital (Profibus or Fieldbus) signal. The temperature sensor and the final control device communicate through the transmitter. Since transmitters provide more robust analog or digital outputs, external signal conditioning and amplification devices are eliminated, thus lowering costs.
The REOTEMP Model W Explosion Proof Field Mounted HART Temperature Transmitter includes a local display, HART compatibility, and a 4-20mA output. The field-mounted transmitter is available as a complete RTD or thermocouple assembly customized to your process.
The REOTEMP Model W includes linearized temperature measurement with TC and RTD sensors (Pt100 and Ni100) inputs, local display, HART communication, and 4-20 mA analog PV output for individual, difference, or average temperature measurement. It can handle two RTD or TC input sensors, and up to 63 transmitters (HART 7) can connect in a multidrop communication setup.

“V” Port Ball Valves for Control and Simplicity
A-T Controls / Triac "V" Series Ball Valves are ideal for achieving more precise control while maintaining simplicity and sealing features. A-T Controls offers 1/2" – 4" 3-piece and 1/2" – 6" flanged sizes. Standard "V" notch angles are 30°, 60°, and 90°. While manual valves are available, A-T Controls specializes in automating them to meet your specific control needs.
V-port valves provide more accurate and consistent control than traditional round ported ball valves.
A-T Controls manufactures "V" port valves with the control port cast and machined into the ball rather than the seat, resulting in significantly improved flow characteristics and the elimination of the need to replace seats. The 30° option provides finer tapered control throughout the valve rotation, while the 60° and 90° options offer a higher Cv as well as controlled flow.
The V7 valves come standard with a PTFE seat, while the V8, V9, and FVD9 V-port valves come standard with a 50/50 STFE seat. The 50/50 SST powder/PTFE blend provides both strength and superior sealing properties.
