When does a plant need an 8-foot flameproof RTD sensor instead of a standard 300mm or 600mm probe?
An 8-foot flameproof RTD sensor becomes necessary when the true process temperature measurement point sits deep inside a tall vessel, long pipeline, or extended tank, 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 — avoiding the extended lead times typically associated with custom long-length sensor fabrication.
This simplex, 3-wire PT100 sensor is built on a 6mm SS316 sheath rated for a -50°C to 250°C process range, a band well suited to water treatment, food and beverage processing, HVAC-adjacent industrial systems, and general utility monitoring applications where moderate-temperature accuracy matters more than extreme high-temperature capability. Class A accuracy keeps the resistance-versus-temperature curve tight and repeatable across the full 8-foot length, and the compacted MgO insulation packed through the probe both accelerates thermal response and shields the internal element from vibration-related fatigue over such an extended run — a genuine engineering consideration that shorter sensors don’t face. The adjustable 1/2″ BSP compression fitting lets installers set precise mounting depth on-site, which matters even more at this length since depth errors are harder to correct after the fact. The die-cast aluminum head carries an IP67 rating with a threaded cap and safety chain to protect the termination compartment from dust and moisture, while the nickel-plated ceramic terminal block ensures a stable, long-lasting wiring connection. This sensor is manufactured by Aavad Instrument Pvt. Ltd. under ISO 9001:2015 certified manufacturing standards and carries CE marking, confirming the product meets applicable EU safety and environmental protection requirements.

FAQs
1. Why is this sensor rated only to 250°C instead of 400°C like other models in the range?This variant is designed for moderate-temperature industrial applications such as water systems, food processing, and beverage processing, where a 250°C temperature range is sufficient for typical process requirements. If your application requires higher temperature capability, consider the 400°C-rated flameproof RTD models available in the same product range.
2. Will an 8-foot probe be too fragile for installation in a vertical tank?
No. The long probe is designed with compacted MgO insulation along the sensing assembly and a durable SS316 sheath that provides mechanical protection and structural strength. However, proper installation practices should be followed for vertical mounting, particularly in high-vibration environments, where excessive unsupported probe overhang should be avoided.
3. Can I get a custom length between 300mm and 8 feet?
Yes. Custom insertion lengths may be available on request. Provide our team with your required insertion depth, application details, and installation requirements, and we can confirm the available configuration and lead time before you place the order.
4. Why should I buy this from Buyinstrument.shop instead of a custom fabricator?
Buyinstrument.shop offers this 8-foot RTD sensor as a ready-stock, factory-tested product where available, with transparent fixed pricing and faster dispatch compared with waiting for a custom fabrication process. The purchase is also supported by Aavad Warranty, 100% Original Products, Secure Payments, and 100% Buyer Protection, providing a straightforward sourcing option for industrial temperature measurement requirements.
