Adding pressure sensors to process cooling equipment is an optional enhancement that offers significant benefits in monitoring and controlling the pressure of heat transfer fluids. These sensors are particularly useful when direct visibility of the machine is limited, preventing easy observation of built-in pressure gauges. Pressure sensors function by measuring the deflection of a diaphragm under pressure and converting this physical change into an electrical signal, which is then communicated electronically. Positioned strategically within the fluid circuit, these sensors relay crucial pressure data to the system’s control unit. This data informs adjustments in fluid flow and other parameters, ensuring optimal pressure and temperature conditions for the cooling process.

The advantages of integrating pressure sensors into process cooling systems are manifold. Real-time monitoring provided by these sensors enables prompt detection and response to pressure fluctuations, aiding in the prevention of equipment damage and downtime, thereby boosting overall efficiency. They are instrumental in maintaining operational safety by ensuring the system stays within safe pressure limits, triggering alarms or shutdowns when necessary to avert hazardous scenarios. Moreover, maintaining consistent pressure levels is key to ensuring product quality, enhancing customer satisfaction and trust.

Despite these benefits, pressure sensors come with considerations. They require periodic calibration to maintain accuracy, which can be time-intensive, and demand specialised skills and tools. Environmental factors like high temperature or corrosive substances may necessitate specialised, and potentially more costly, sensors. Regular maintenance, including cleaning and part replacement, is essential for their functionality, adding to overall costs. Moreover, incorporating pressure sensors can increase both price and lead time of unit production. When deciding to add pressure sensors, these factors must be weighed against the operational benefits that they offer, ensuring that they align with the specific needs and constraints of the cooling system.
