Description
PT100 RTD Sensor with NABL-Accredited Calibration Certificate (Model APWD-6) is a precision duplex PT100 temperature sensor developed for industrial applications where measurement traceability, calibration documentation, and quality assurance are as important as temperature accuracy. Featuring Duplex Class A PT100 sensing elements (3+3 wire), a corrosion-resistant SS316 stainless steel probe, a durable IP65 die-cast aluminium terminal head, and a compact 150 mm immersion length, this industrial RTD sensor delivers reliable temperature measurement across an operating range of -50°C to +400°C. The sensor can be supplied with an NABL-accredited calibration certificate, providing calibration results that are traceable to national measurement standards in accordance with accredited laboratory procedures.
Designed for industries operating under GMP, ISO, quality management, and validation requirements, this RTD sensor helps support calibration records, audit documentation, preventive maintenance programs, and instrument verification procedures. The duplex (3+3 wire) PT100 configuration provides two independent sensing elements, enabling process control and redundant monitoring from a single installation point. Manufactured by Aavad Instrument, this calibrated PT100 RTD sensor is suitable for pharmaceutical manufacturing, food and beverage processing, biotechnology, laboratories, chemical plants, OEM equipment, and industrial quality systems requiring documented temperature measurement performance and traceable calibration.

FAQs
1. What does it mean to buy a PT100 RTD Sensor with NABL-accredited Calibration?
A PT100 RTD Sensor with NABL Traceable Calibration is supplied with a calibration certificate that is traceable to national measurement standards through procedures followed by a National Accreditation Board for Testing and Calibration Laboratories (NABL) accredited laboratory. This provides audit-ready calibration documentation for GMP, ISO, quality assurance, and validation requirements, offering greater confidence than a standard non-traceable factory calibration.
2. What are the specifications of this NABL-Calibrated PT100 Sensor?
Aavad’s Model APWD-6 is a duplex (3-wire + 3-wire) PT100 RTD Sensor with Class A accuracy and an operating temperature range of -50°C to +400°C. It features a 150 mm immersion length, an SS316 stainless steel sheath, and a die-cast aluminum IP65 terminal head for reliable industrial temperature measurement.
3. Why is this Sensor described as a “Cost-Optimized Non-Flameproof Design”?
This sensor uses a standard non-flameproof terminal head instead of an explosion-proof enclosure, making it a cost-effective solution for non-hazardous industrial environments. It delivers the same Class A PT100 measurement accuracy while reducing overall equipment cost for applications where hazardous-area certification is not required.
4. What industries most benefit from NABL Traceable Calibration Documentation?
NABL Traceable PT100 RTD Sensors are widely used in pharmaceutical manufacturing, food and beverage processing, quality assurance laboratories, calibration laboratories, biotechnology, chemical processing, OEM equipment, and other GMP- or ISO-compliant industries where calibration traceability, instrument verification, and regulatory compliance are essential.
5. Can this Sensor be used for Redundant or Dual-Circuit Monitoring?
Yes. The duplex (3-wire + 3-wire) PT100 configuration provides two independent temperature sensing circuits within a single 150 mm probe. One sensing element can be connected to the primary PLC, DCS, or process controller, while the second can simultaneously support backup monitoring, alarm systems, safety interlocks, or data logging.
