The sensing head is positioned between the heating elements. High ambient temperatures mean that PyroMini JA (up to 120°C ambient) and HA (up to 180°C ambient) models are most suitable. No cooling is required for the sensing head.
The production rate is often limited by the cooling time. The sensor monitors the surface temperature of the formed part as it is cooled with an instantaneous 240 ms response time, so the operator or control system can see immediately when the part is cool enough and remove it quickly.
The optional touch screen display provides a large, bright indication of measured temperature, 2 alarm relay outputs, and data logging to a MicroSD Card. The sensor is fully configurable via the touch screen.
For connection to a PLC or temperature controller, two output types are available: 4 to 20 mA or RS485 Modbus.
Calex can also provide other thermoforming temperature systems ranging from a single sensor with a PID controller, to a digital network of hundreds of sensors, with display, control, alarm, analogue output and data acquisition functions.
