2~12 Points-Customized Multipoint Thermocouple

Multipoint Thermocouples can measure the temperature of multiple monitoring points at the same time, also called multipoint temperature sensors. It is suitable for temperature measurement at multiple locations or at a single location where the temperature gradient is not significant at the production site and must be measured at the same time.

Our Sino-Inst Multipoint Thermocouples support customization of 2 to 12 temperature measurement points, as well as customization of the temperature probe length. It is widely used in large fertilizer synthesis towers, storage tanks and other devices.

Models and Specifications

3. Multi point thermocouple (thermal resistance)

Multi-point thermocouples (resistance) are suitable for production sites where the temperature gradient is not significant and multiple locations need to be measured at the same time or multiple measurements at a single location.

Products are widely used in synthesis towers, reactors, storage tanks and other devices.

According to the structure of the temperature measuring element, it can be divided into bundled type, single-point sealed type, multi-point composite type, etc.

4. Rigid multi point thermocouple (thermal resistance)

Rigid multipoint thermocouple (thermal resistance) is suitable for applications in the oil, gas and chemical industries.

1. Can be customized for different working conditions. Only one process connection is required to monitor temperatures at multiple measuring points on the same line. Improved process safety. System integration is simple, reducing installation time.
2. Equipped with an outer protective sleeve with high mechanical strength and an independent armored core that is easy to replace, suitable for both thermal resistors and thermocouples.
3. The armored core complies with IEC 60584 and IEC 60751 standards and is easy to integrate.
4. Modular product structure to provide user-customized products. Flexible to use, simple to install and maintain.
5. Meet explosion-proof requirements.
6. Maximum insertion depth: 15000 mm.
7. Maximum process pressure (static pressure): at 20 °C: 240 bar.

Typical applications

Our Sino-Inst’s multipoint thermocouples are successfully used in the 10,000-ton o-xylene reactor in the phthalic anhydride workshop of the coking plant. The outer diameter of the armored integral multipoint thermocouple used is Ф8mm/14 measuring points.

Some companies use armored integral multipoint thermocouples with an outer diameter of Ф4mm/6 measuring points and an outer diameter of Ф3mm/4 temperature measuring points, etc.

More Featured Temperature Sensors and Measurement Solutions

Multipoint Thermocouple assembles multiple independent micro-armored insulated thermocouples in an outer protective tube, and then the entire product outer protective tube is drawn to the outer diameter required by the user.

The outer diameter of the armored integral multi-point thermocouple is usually Ф6-Ф8mm. With its advantages of high technical difficulty, sophisticated production technology, reliable product quality, and perfect after-sales service, it has become a popular choice in the chemical industry (fertilizer industry synthesis tower, reaction tank), metallurgy, petrochemical, High quality temperature sensor for gas industry applications.
