Precision Temperature & Measurement Solutions for Industry
ALF-Sensor specializes in the design and manufacture of high-quality temperature sensing and measurement products for industrial applications. With a strong focus on accuracy, durability, and compliance with international standards, ALF-Sensor solutions are trusted across power generation, oil & gas, chemical processing, manufacturing, and automation industries.
High-Accuracy Temperature Sensing
Resistance Temperature Detectors (RTDs)
ALF-Sensor RTDs, including Pt100, Pt500, and Pt1000 types, provide highly accurate and stable temperature measurement by detecting changes in electrical resistance. These sensors are ideal for applications requiring long-term precision and repeatability, even under fluctuating process conditions.
RTDs are available in various configurations, such as threaded, flanged, or customized process connections, with optional protection tubes and head assemblies. Their robust construction allows reliable operation in pipelines, tanks, and industrial machinery where accuracy and consistency are critical.
Extreme-Temperature Measurement
Thermocouples & Thermoelements
ALF-Sensor thermocouples measure temperature by generating a voltage from two dissimilar metals, making them suitable for extremely high-temperature environments. They are widely used in furnaces, boilers, kilns, and heavy industrial processes where fast response and durability are essential.
Available in multiple types, sheath materials, and mounting styles, these thermocouples are engineered to perform reliably in harsh conditions such as vibration, pressure, and corrosive atmospheres. Explosion-proof and custom designs ensure safe and flexible installation across demanding applications.
Smart Signal Conversion & Monitoring
Temperature Transmitters & Digital Sensors
ALF-Sensor temperature transmitters convert raw signals from RTDs or thermocouples into standardized outputs such as 4–20 mA, enabling seamless integration with PLCs, DCS, and SCADA systems. These transmitters ensure stable, noise-free signal transmission over long distances.
Designed for accuracy and reliability, ALF-Sensor transmitters support advanced diagnostics and configuration options. Digital temperature sensors further enhance monitoring capabilities by providing precise data for modern automation and industrial control systems.
Process Protection & Sensor Safety
Thermowells & Protection Fittings
Thermowells and protection fittings from ALF-Sensor are designed to shield temperature sensors from direct exposure to process media. They protect sensing elements against high pressure, high flow velocity, corrosion, and mechanical stress, significantly extending sensor lifespan.
Manufactured from high-grade stainless steel and special alloys, ALF-Sensor thermowells are available in threaded, flanged, and welded designs. These components ensure safe maintenance and replacement of sensors without interrupting the process, making them essential for critical industrial applications.
