FAQs
1. What is an RTD Sensor with Mini Head used for?
An RTD Sensor with Mini Head is a compact PT100 Resistance Temperature Detector (RTD) designed for tight installation spaces where a standard connection head cannot be accommodated. Aavad’s Mini Head RTD Sensor (Model APMS) features an SS316 stainless steel construction with a 3 mm OD probe and 80 mm insertion length, making it ideal for small equipment, control panels, machinery, and other applications with limited mounting clearance.
2. What is the temperature range and accuracy of Aavad’s Mini Head RTD Sensor?
The Aavad Mini Head RTD Sensor (Model APMS) measures temperatures from -50°C to +250°C with Class A PT100 accuracy, providing precise, repeatable, and reliable temperature measurement for industrial, laboratory, OEM, and process control applications.
3. What connection type does the RTD Sensor with Mini Head use?
This Mini Head PT100 RTD Sensor features a fixed 1/2" BSP (Male) process connection with a single cable entry and a nickel-plated ceramic terminal block. It is designed in a simplex configuration and supports 2-wire or 3-wire PT100 wiring for accurate industrial temperature measurement.
4. Is the Mini Head RTD Sensor suitable for high-vibration or compact machinery?
Yes. The miniature protection head and SS316 stainless steel construction make this RTD sensor ideal for high-vibration, compact machinery, motors, small pipelines, equipment panels, and confined industrial installations where a conventional head-type RTD cannot be easily installed.
5. Does Aavad Instrument customize the Mini Head RTD Sensor for specific lengths or connections?
Yes. Aavad Instrument manufactures Mini Head PT100 RTD Sensors with custom probe lengths, tip diameters, process connections, cable configurations, and sensing elements to meet specific industrial and OEM application requirements, in addition to the standard 80 mm length, 3 mm OD, and 1/2" BSP (Male) configuration.
