[ Focus on Chemical Machinery Equipment Network ] Innovations in temperature sensors , calibration and related equipment help ensure reliable and safe operation of the plant!
Chemical machinery equipment network hotspots focus on chemical machinery equipment sensorsTemperature is one of the most important process parameters that need to be measured and controlled in the chemical processing industry (CPI)
.
For this reason, suppliers continue to improve temperature sensors, transmitters, and related hardware and software to ensure accurate and reliable measurements, while ensuring the safety of the factory
.
Although traditional thermocouples and resistance temperature detectors (RTDs) are analog in nature, digitization has now become "a matter of course", and the Industrial Internet of Things (IIoT) and Industry 4.
0 trends go hand in hand with manufacturing processes and process equipment that is more reliable

"The main trends in temperature measurement in the past few years have revolved around safety, digital transformation, and innovation," said Kevin Stultz, global product manager at Emerson Rosemount Temperature (St.
Louis, Missouri).
"New software and digital tools are becoming increasingly popular in the industry.
The more common, because customers want more data about their processes and faster services, which leads to the need to reduce complexity and increase the speed of innovation

Calibration progress
Calibration progressAlthough the characteristics and operation of traditional thermocouples and RTDs are well known, they still require calibration—not just the first time after the sensor is made, but also regular calibration to solve the aging problem that may cause drift
.
In some CPI industries, such as pharmaceuticals, food and beverages, and life sciences, regular calibration is both a standard and a regulatory requirement
.
Since the sensor usually needs to be removed from the process to be calibrated, this process is both destructive and time-consuming

Ned Espy, Technical Director of Beamex, Inc.
(Marietta, Georgia), said: "Now, with IIoT, we can get calibration data in digital format-every number is recorded, so you can do some cool With analysis, you can compare temperature probes over time, or compare different probes over time
.
With this information, you may find that you can extend the time interval between calibrations

People are becoming more aware of data integrity issues and minimizing human error
.
The calibration data is recorded according to observations, so there is no human error
.
Our system is highly automated, so users can avoid using paper

Launched in 2019, Beamex MC6-T (Figure 1) is a portable automatic temperature calibration system that combines advanced temperature drying blocks and Beamex MC6 multifunctional process calibrator technology
.
Espy said that it can generate temperature, as well as measure and simulate temperature and electrical signals, providing a unique combination of functions
.
MC6-T is a recording calibrator and communicates with calibration software
.
This enables a digital and completely paperless calibration process

According to Endress+Hauser, iTHERM TrustSens integrates a high-precision reference with long-term stability into the temperature sensor itself
.
The reference material has a unique and fixed point, which is the temperature, in which the ferromagentic nature of the material changes drastically
.
This characteristic change can be detected electronically, and the point at which TC is reached can be determined and used as a reference temperature for calibrating the Pt100 sensor

.
The exact TC of the reference material is determined by each sensor with extremely high accuracy (usually about 118.
0°C), so every time the cooling process is started at a higher temperature, such as steam sterilization of plants, the sensor is automatically calibrated
.
If the measurement deviation between the reference and the sensor exceeds the set limit, the device will send an alert message, which will also be displayed on the device as a flashing red LED

If the measurement deviation between the reference and the sensor exceeds the set limit, the device will send an alert message, which will also be displayed on the device as a flashing red LED
.
Since steam sterilization is usually carried out daily, calibration is performed much more frequently than manual calibration intervals determined based on risk assessment
.
This saves a lot of time and money, because calibration does not require any personnel costs or additional planned downtime
