The AlphaLimpetTMincorporates a microprocessor built within the heater block, giving the heater the ability to look after itself and to control temperature based on an internal, user-adjustable set-point.
The AlphaLimpet also allows a user to override the internal set-point, monitor the spare temperature sensor port and control the unit externally just as a heater using ON/OFF control and a separate temperature sensor.
A Limpet can also be used in “Master” or “Slave” mode, so that an AlphaLimpet, being controlled either by an internal setpoint or an external ON/OFF signal, can drive a series of slaves (either BetaLimpets or MicroLimpets) from the same connection.
If desired, the user can wire up Limpets in a combination of Master / Slave (either internally or externally controlled) and can even stagger set points to generate a gradient heat profile on the workpiece that is being heated.
The user can monitor the heater’s status using a simple linked-together healthy signal. This is often critical for users and no other known system provides a single, self-contained heating block with such flexibility and reporting ability without hooking on an external control system, i.e., there is no need for a control panel.
Unless it can be mounted onto a flat surface, a Limpet must normally be used in combination with a profiled adapter block, which gives a direct heat flow path to the workpiece shape, hence being able to heat a myriad of equipment surfaces by the use of a correctly-profiled metal adapter block (usually aluminium). The adapter block also serves as an effective heat storage device, thereby enhancing the mass of heat flow into the workpiece under varying cooling loads. We make a range of standard adaptor blocks that will fit most common items and radii but we can also produce custom-profiled blocks, as required.
