Temperature Sensors Ireland — The Right Sensor Prevents Costly Process Failures

A process running at the wrong temperature costs you in scrap, downtime, or product recalls. Whether you need a thermocouple for a furnace, a PT100 RTD for pharmaceutical process monitoring, or an NTC thermistor for HVAC control, Thermelec has the correct temperature sensor in stock — and the technical expertise to make sure you get it right first time.

Types of Temperature Sensors Thermelec Supplies in Ireland

Sensor Type	Range	Best Application	Accuracy
Thermocouple (Type K)	-200°C to +1260°C	Furnaces, kilns, industrial ovens	±0.4% FS
Thermocouple (Type J)	-40°C to +750°C	Plastics processing, HVAC	±0.75% FS
RTD / PT100	-200°C to +600°C	Pharmaceutical, food, labs	±0.1°C
PT1000	-50°C to +400°C	Building management, HVAC	±0.3°C
NTC Thermistor	-40°C to +150°C	HVAC, refrigeration, domestic	±0.2°C
Infrared (Non-contact)	0°C to +500°C	Moving targets, hazardous areas	±1%

What Happens When You Use the Wrong Temperature Sensor?

• Product out-of-spec — food, pharma, and plastics processes require precise temperature accuracy
• Sensor burnout — selecting a sensor outside its rated temperature range causes premature failure
• Incorrect readings — using a Type K thermocouple with a Type J input causes measurement error
• Regulatory non-compliance — HACCP, GMP, and ISO processes require validated temperature measurement
• Costly unplanned downtime — a failed sensor in a continuous process line stops production
  

Frequently Asked Questions — Temperature Sensors Ireland

What is the difference between a thermocouple and an RTD sensor?

A thermocouple measures temperature by generating a small voltage at the junction of two dissimilar metals — it is rugged, fast-responding, and works over a very wide range (-200°C to +1260°C). An RTD (Resistance Temperature Detector) measures temperature through electrical resistance change — it is slower but significantly more accurate (±0.1°C), making it the preferred choice for pharmaceutical, food, and laboratory applications.

What is a PT100 sensor?

A PT100 is a type of RTD with a resistance of 100 ohms at 0°C. It is the most widely used precision temperature sensor in industrial applications across Ireland and Europe, particularly in food processing, pharmaceuticals, and building management systems.

Do you supply custom-length thermocouple probes?

Yes. Thermelec can supply temperature sensors in custom insertion lengths, sheath diameters, and connection head types. Contact our technical team with your specifications.

Can I use a temperature sensor with any controller?

No — the sensor type must match the controller input. A Type K thermocouple requires a Type K input on your controller. An RTD/PT100 sensor requires an RTD input. Thermelec supplies matched sensor and controller combinations to eliminate compatibility errors.
