How do you choose the right insertion length for a mineral insulated RTD sensor on a larger pipeline or process vessel?
A 900mm mineral insulated RTD sensor offers enough reach for larger pipelines and mid-to-large vessels while remaining practical to handle and install, and this PT100 model is available from Buyinstrument.shop at a transparent, factory-direct fixed price with zero middleman markup and ready stock for fast nationwide dispatch.
This simplex, 3-wire PT100 sensor uses compacted MgO (mineral) insulation packed through the full 900mm probe length, a construction method that improves thermal response speed and shields the internal element from vibration and mechanical shock — a meaningful durability advantage in rotating equipment areas and high-vibration installations compared to non-mineral-insulated sensors. Built from SS316, the sensor is rated for a -50°C to 400°C operating range with Class A accuracy, delivering the repeatable, tight-tolerance readings required for both process indication and closed-loop control applications. The IP67-rated die-cast aluminum head, complete with a threaded cap, safety chain, and single 1/2″ NPT (F) cable entry, keeps the termination compartment fully sealed against dust and moisture ingress, making this sensor suitable for both indoor process areas and semi-exposed outdoor installations. The 1/2″ BSP adjustable compression fitting lets installers fine-tune insertion depth on-site, and the nickel-plated ceramic terminal block ensures a stable, corrosion-resistant wiring connection for years of service. This sensor is manufactured by Aavad Instrument Pvt. Ltd. under ISO 9001:2015 certified manufacturing standards and is CE marked, confirming it meets applicable EU safety, health, and environmental protection requirements.

FAQs
1. What does “mineral insulated” mean and why does it matter?
Mineral insulated means that compacted magnesium oxide (MgO) is packed inside the sensor sheath around the PT100 sensing element and internal conductors. This construction provides efficient heat transfer for a fast temperature response while helping protect the internal wiring against vibration and mechanical shock, supporting reliable operation and longer sensor service life in demanding industrial environments.
2. Is 900mm suitable for a standard 6-inch or larger pipeline?
Yes. A 900mm insertion length provides substantial reach for many standard-to-large pipeline installations and medium-sized vessels. For very large-diameter pipelines, deep vessels, or applications requiring greater penetration into the temperature zone, longer variants such as 1200mm, 2400mm, and 3000mm may be more appropriate.
3. Does this sensor come with a thermowell?
No. This is a direct-mount RTD sensor and does not include a thermowell. If you require a removable and serviceable installation where the sensor can be accessed without opening the process connection, consider a Flameproof RTD Sensor With Thermowell or contact our team to identify a compatible thermowell for this sensor.
