When is a simplex PT100 sensor the smarter choice over duplex for mid-to-large vessel temperature monitoring?
For applications where redundancy isn’t strictly required but extended reach is, a simplex 1200mm PT100 sensor offers a cost-efficient, straightforward solution, and this model is available from Buyinstrument.shop at a transparent, factory-direct fixed price with zero middleman markup and ready stock for fast nationwide dispatch.
Built with a single 3-wire PT100 circuit in an SS316 sheath packed with compacted MgO insulation, this sensor delivers a -50°C to 400°C operating range with Class A accuracy, providing the tight, repeatable resistance-temperature relationship required for general process monitoring, control loop integration, and routine plant indication. The 1200mm insertion length covers most mid-to-large vessels, tall reactors, and extended pipeline sections that a shorter 300mm or 600mm sensor cannot properly reach. The IP65-rated die-cast aluminum head, fitted with a threaded cap, safety chain, and 3/4″ ET cable entry, provides solid protection against dust and splash exposure in general industrial environments, while the 1/2″ BSP adjustable compression fitting allows engineers to fine-tune insertion depth during installation. The nickel-plated ceramic terminal block ensures a stable, corrosion-resistant connection point for the sensor’s service life. 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. Should I choose this simplex model or the duplex version at the same length?
Choose the simplex RTD sensor when your application does not require measurement redundancy and you want a simpler, more cost-effective configuration. Choose the duplex version, such as the PT100 Temperature Sensor 6x1200D, when you require a built-in secondary PT100 circuit for backup measurement, critical control loops, or applications where sensor redundancy is important.
2. Is 1200mm long enough for a large storage tank?
A 1200mm insertion length is suitable for many mid-to-large storage vessels, process tanks, and reactors. For extra-deep tanks, tall columns, or applications where the temperature sensing point is located significantly deeper inside the vessel, longer variants such as 2400mm and 3000mm may be more appropriate. If you are unsure about the required insertion length, contact our team with your vessel dimensions and installation details.
3. Can this sensor be connected directly to a PLC or DCS input?
Yes. The 3-wire PT100 output can be connected to compatible PLC and DCS RTD input modules or dedicated RTD input cards commonly used in industrial automation systems. Ensure that the selected PLC or DCS input module supports the PT100 sensor type, 3-wire configuration, and required measurement range before connection.
