The CAL 3300 temperature controller from West Control Solutions is controlling the performance of an incubation chamber for laboratory equipment manufacturer Solent Scientific.

The 37º Incubation Chamber from Solent is an acrylic enclosure integrated with a microscope. It is used to conduct prolonged studies of living cells, usually involving time-lapse image capture. The enclosures can also exclude light when working with low-level-light microscopy.

Warm, filtered air circulates within the enclosure from a heater unit and the precise temperature within the chamber is controlled by a CAL 330 unit.

Orry Dugdale, director at Solent Scientific, said that when the company built the 37° Incubation Chamber, it was trying to create a cell-culturing system that accurately replicates conditions within the human body, which means maintaining a constant temperature.

The temperature requirement for the chamber is 37ºC, ±0.1ºC. The temperature must be accurate and within this tight tolerance. According to West Control Solutions, the CAL 3300 is proven to be capable of meeting this requirement.

Key benefits of product application

  • The CAL 3300 temperature controller is said to be easy to operate.
  • Its large four-digit green LED screen shows current temperature.
  • A parameter security locking feature prevents the operator from inadvertently changing settings.
  • The controller offers integrated auto-tune PID control, meaning users do not have to program parameters manually.
  • The derivative approach control function prevents control temperature overshoot during warm-up.
  • Communication software for the real-time logging of CAL controllers allows Solent to prove that the temperature within the incubator was kept to the correct level over long periods of time.
  • West Control’s solution avoided the considerable cost and development involved in employing SCADA packages.

Controllers are available in 1/32, 1/16, 1/8 and 1/4 DIN sizes. There are also a number of DIN-rail-mounted controllers available. At the heart of all product designs from West Control Solutions is exact, accurate temperature control in easy-to-use products complemented with excellent reliability and durability.

West Control Solutions works with a global base of equipment manufacturers and end users. The products are ideally suited to challenging and tough environments such as industrial ovens, furnaces and kilns, plastics and extrusion. As the products offer excellent levels of precise control and accuracy together with being attractive instruments with strong aesthetic consideration during design they are often commonly used in laboratory, testing equipment and food and beverage applications.

The products are supported by a dedicated team of technical support specialists. The team has more than 25 years’ experience in temperature control instrumentation, specifically supporting products in industrial applications. This knowledge provides customers with complete peace of mind that they will be able to maximise the functionality available within the products even for the most complex of applications.

In addition to the core product offering there is also a customisation team that is available for those occasions where a custom controller will fit your requirements better than a standard product. In these cases, a comprehensive specification will be created, considering all requirements relating to the look and feel of the instrument, the format and functionality that is required. For the majority of customisation projects either a standard controller or a previous custom design can be used as the starting point for the bespoke design. This allows customers to benefit from reduced design and manufacturing costs, resulting in more customers to gain competitive advantage through unique designs and advanced functionality.
