Application guide
Industrial Temperature Monitoring in the UAE & GCC
Measure pipes, vessels, bearings and process lines with the right sensor, thermowell and transmitter. We supply RTD and thermocouple assemblies, thermowells, smart transmitters and digital gauges, including hazardous-area versions.
Which temperature measurement setup do you need?
Decide where the sensor mounts, how the signal leaves it and whether the area is hazardous.
| Your situation | Start with | Why |
|---|---|---|
| High pressure or high-velocity pipe | Solid drilled weld-in thermowell with RTD | The WTW101 thermowell is machined from solid bar for strength, in 316 stainless steel, Alloy C276, Alloy 400 or Alloy 600. Wake frequency calculations per ASME PTC 19.3 TW-2016 are offered. |
| Pipe that must not be penetrated | Strap-on surface RTD | The RTD720 straps onto pipe or tube with a hose clip band and covers -196 to +650 °C with 1/10 DIN to class B accuracy. |
| Bearing temperature on rotating machinery | Oil-tight bearing RTD | The RTD580 is an immersion RTD with a transition barrier that prevents oil leakage, and ships with a pressure test certificate. |
| Signal to a PLC or DCS | 4-20 mA transmitter | The HBS6000 combines a Pt100 or Pt1000 RTD with a 4-20 mA transmitter and PC programming. The TTR200 is a smart in-head transmitter for RTD inputs. |
| Reading and alarms at the point of measurement | Digital temperature gauge | The DM670TM shows temperature on a 6-digit display, has two volt-free relays and records up to 5,000 data points. |
| Zone 1 or Zone 2 area | ATEX / IECEx transmitter or approved assembly | The SEM320X is ATEX, IECEx and UKEX approved with HART and a local display. The TTR200X is the approved version of the TTR200. The RWA101 assembly carries hazardous-area approvals. |
RTDs give better accuracy over a narrower range, and thermocouples cover higher temperatures and respond faster. Choose by your accuracy and temperature needs.

How to specify a temperature sensor
Six questions that decide the assembly.
- What temperature range?The range decides sensor type, cable and insulation. RTDs suit moderate ranges, thermocouples reach higher.
- What accuracy do you need?RTDs come in classes from 1/10 DIN to class B. Pick the class for the job.
- What is the process pressure and velocity?High pressure and flow need a solid drilled thermowell, with a wake frequency check.
- What material touches the process?Match the thermowell to the process: 316 stainless, C276, 400 or 600.
- How is the signal used?Choose a direct sensor, a 4-20 mA or HART transmitter, or a local display with relays.
- Is the area classified?Hazardous areas need ATEX or IECEx approved sensors and transmitters. Give the zone and gas group.

Industrial temperature monitoring FAQs
Should I use an RTD or a thermocouple?
RTDs give higher accuracy and stability over moderate ranges. Thermocouples cover higher temperatures and respond faster. Pick by your range and accuracy needs.
Why do I need a thermowell?
A thermowell protects the sensor from pressure, flow and the process fluid and lets you remove the sensor without draining the line. High-velocity lines need a wake frequency check.
What is a wake frequency calculation?
It checks whether vortices shed by flow past the thermowell could make it vibrate at its natural frequency. HB Sensors offers calculations per ASME PTC 19.3 TW-2016.
Do you supply temperature transmitters for hazardous areas?
Yes. The Status SEM320X and TTR200X are ATEX, IECEx and UKEX approved. Tell us the zone and gas group and we will check the certificate.
Can I log temperature without a PLC?
Yes. The Status DM670TM gauge and the SEM710TM transmitter have built-in datalogging that records up to 5,000 points.
Do you supply temperature instruments across the GCC?
Yes. Daly Middle East supplies from Dubai to the UAE, Saudi Arabia, Oman, Qatar, Kuwait and Bahrain.
Need temperature instruments for a plant in the UAE or GCC?
Send us the process, range, accuracy, connection and area classification. We will recommend the assembly and quote it.
