The PT100-3 is a versatile temperature sensing solution suited to a broad range of industries and processes where robust construction and accurate measurement are essential.

• Industrial Process Control. The sensor’s stainless steel probe and sealed connection box make it ideal for monitoring temperatures in pipelines, pressure vessels, and manufacturing machinery, where vibration and exposure to process media are common.
• Chemical and Petrochemical Processing. The PT100-3 withstands the corrosive atmospheres and elevated temperatures found in reactors, distillation columns, heat exchangers, and storage tanks, providing stable readings critical to process safety and product quality.
• Oil and Gas. With NPT-compatible fittings and a wide operating range, the sensor integrates seamlessly into upstream, midstream, and downstream equipment, including wellheads, separators, and transmission pipelines.
• Power Generation. The sensor is well suited for temperature monitoring in boilers, steam turbines, cooling systems, and transformer oil, where continuous and reliable measurement is essential for plant efficiency and safety.
• HVAC and Building Automation. The PT100-3 can be installed in large commercial and industrial HVAC systems, chilled-water loops, and district heating networks to provide accurate temperature feedback for energy management.
• Food and Beverage Processing. The hygienic stainless steel probe and sealed head allow the sensor to be used in pasteurisation, sterilisation, and storage applications, where cleanliness and measurement accuracy are equally important.
• Pharmaceutical Manufacturing. Precise temperature control during synthesis, fermentation, and lyophilisation processes is supported by the sensor’s high accuracy and EN 60751 compliance.
