RTD 43 Flexible Spring Bayonet Style RTD (Resistance Temperature Detector) consist of a long flexible SS spring along with bayonet cap locking mechanism mounted on wire. This arrangement allows for spring loading of temperature measuring tip and facilitates firm contact of tip with the surface to achieve fast response and accurate temperature readings. This construction is designed to withstand vibration, movement and challenging mounting conditions, this RTD delivers consistent performance in harsh applications.
Key Features:-
- Spring-Loaded Tip – Ensures consistent contact with the measuring surface for improved accuracy and faster response times.
- Accommodates variations in installation depth by applying constant pressure.
- Most suited for installations requiring movement or frequent adjustments.
- Typically operating ranging is from -50°C to 500°C, depending on insulation and sheath material.
- Available in 2-wire, 3-wire, or 4-wire configurations for enhanced accuracy and reduced lead wire resistance errors.
- Available in Insulations like Teflon (PTFE), Fiberglass, or PVC based on environmental requirements.
- Typically uses Pt100 or Pt1000 elements with Class A or B accuracy (per IEC 60751).
- Insulation Resistance : 100 MG Ohms @ 250 vdc
- Response Time : <5 Sec in circulating water @ 1ft/sec
- Accuracy : As per IEC60751 (See tolerance chart)
- Self Heating Error: < 0.30°F (0.17°C)
- Time Constanat : < 5 sec
Application Note
RTD43 is widely used across various industries for precise temperature monitoring and control. In the plastic and rubber industry, RTDs are employed in extruders, injection molding machines, and hot runners to monitor and regulate process temperatures, ensuring quality and consistency. In the automotive sector, RTDs play a vital role in engine, gearbox, and exhaust temperature monitoring during testing and production setups, contributing to the reliability and performance of vehicles. They are also used in boilers, turbines, and generators to optimize efficiency and ensure effective temperature management. Additionally, RTDs are critical in the food and beverage industry, where they ensure precise temperature control during processing and storage, meeting strict hygiene and safety standards.
