Increasing Safety in the Food Industry with Wireless Solutions

The purity of ingredients is vital for all manufacturing processes, but it is particularly critical for personal care products and food. These processes regularly need pipes for transporting liquid to the production line. However, chemical and physical residues must be routinely removed from the pipes in order to maintain quality standards. Cleaning the pipes usually involves pumping water or some other cleaning liquid through the pipes at a preferred temperature range. Wireless monitors can enhance the accuracy of this temperature and automatically offer alerts if the temperature falls out of range.

Problem

A multinational manufacturer of household and personal care products needed to maintain the temperature of the cleaning liquid within one degree Celsius (C) of the target temperature. This requirement was particularly difficult to obtain given that the temperature of the operating environment could range from 20 to 85 ºC (68 to 185 ºF). This manufacturer could not ensure the pipe had been cleaned appropriately if it could not guarantee that the water temperature remained within the preferred range throughout the length of the pipe. The key problem with this requirement existed in attaining a method for accurately measuring the water’s temperature through the whole pipe.

Solution

The solution existed in installing a wireless temperature monitoring system from OMEGA such as the wireless transmitters and receivers with extended distance. These systems comprise of a series of temperature sensor probes positioned along the pipe that capture and then transmit the temperature of the cleaning liquid. For instance, the RTD-to-wireless connector transmitter system has more than 70 surface temperature sensors and a 48-channel receiver for receiving the temperature data from these sensors; OMEGA software then tracks this data and logs it in real-time.

Results

It is possible to preset the preferred temperature range of the water so that alarms can then alert operators to the problem if the water temperature varies beyond this acceptable range. The OMEGA product solutions are wireless, allowing the temperature probes to be effortlessly moved to other pipes as required without removing or installing wiring. Thus, the customer can guarantee that the pipes have been cleaned based on the desired specifications.
