What makes a flameproof RTD PT100 sensor the right choice for temperature measurement inside a hazardous or Zone-rated process area?
A flameproof RTD PT100 sensor is designed to safely measure process temperature in areas where flammable gases or vapors may be present, and this 6x300mm model from Buyinstrument.shop is available at a transparent, factory-direct fixed price with zero middleman markup, ready stock, and nationwide dispatch — built specifically for engineers who need a compact, hazardous-area-ready sensor without the extended lead times of custom OEM ordering.
This simplex, 3-wire PT100 sensor is constructed with an SS316 probe and compacted MgO insulation, giving it strong corrosion resistance and a fast, stable thermal response across its -50°C to 400°C working range, with Class A accuracy ensuring the resistance-temperature relationship stays tight and repeatable — essential for safety instrumented systems and process interlocks that depend on trustworthy readings. The 300mm insertion length makes it well suited for shallow pipeline taps, compact vessels, skid packages, and retrofit installations where a longer probe isn’t required. A key differentiator on this specific variant is the SS cable gland fitted at the 1/2″ NPT (F) cable entry, which provides a mechanically secure, sealed termination that resists vibration loosening and moisture ingress better than a standard unsealed entry — a detail that matters when the sensor is installed in high-vibration rotating equipment areas or outdoor hazardous zones. The die-cast aluminum head carries an IP67 rating with a threaded cap and safety chain, and termination is made onto a nickel-plated ceramic terminal block for long-term corrosion-free contact. This sensor is manufactured by Aavad Instrument Pvt. Ltd. under ISO 9001:2015 certified processes, and it carries CE marking confirming conformity with applicable EU safety and health protection standards — documentation industrial buyers increasingly require during vendor qualification.

FAQs
1. Does this sensor need a separate flameproof enclosure to be used in a hazardous area?
The sensor features a flameproof-ready head design intended for industrial applications where hazardous-area requirements may apply. However, the final suitability depends on the site’s hazardous-area classification, zone requirements, certification, installation method, and applicable standards. Always confirm the required zone classification and certification with your site safety officer or qualified hazardous-area professional before final installation.
2. What’s the benefit of the SS cable gland over a standard cable entry?
The SS cable gland provides a secure mechanical seal at the 1/2″ NPT cable entry, helping reduce the risk of moisture ingress, cable movement, and pull-out. This is particularly useful in applications exposed to vibration, rotating equipment, outdoor conditions, or demanding industrial environments, where a secure cable termination is important for reliable operation.
3. Is 300mm insertion length enough for my pipeline?
A 300mm insertion length is suitable for many shallow pipeline taps, small vessels, skid-mounted equipment, and compact process installations. For deeper tanks, vessels, or larger pipe diameters, longer insertion lengths may be required. The same Head Type RTD Sensor range is available in longer variants such as 600mm, 900mm, 1200mm, and beyond, depending on the application requirements.
4. Why should I buy from Buyinstrument.shop instead of a local distributor?
Buyinstrument.shop provides a direct purchasing channel for industrial instrumentation with transparent factory-direct pricing, ready-stock availability where applicable, and product support from Aavad Instrument. Buyers also receive purchase confidence through Aavad Warranty, 100% Original Products, Secure Payments, and 100% Buyer Protection, providing a straightforward sourcing experience for industrial temperature sensors.
