3. MTC-20/2S System
3.1. System
Description
The MTC-20/2S
temperature control system is designed for heating purposes in
electrophysiological experiments. The MTC-20/2S system is housed in small desktop cabinet
that can be placed close to the microscope, with built-in power supply and cooling elements
for the power devices. The system guarantees low noise operation and has special protection
features to prevent the preparation from damage.
The MTC-20/2S
incorporates two electronic thermometers for small semiconductor sensors
(R2252, i.e. the sensor has a resistance of 2252
Ω
at 25 °C), two digital temperature displays
(XX.X °C), a set-point control with digital readout (XX.X °C), a PI (proportional-integral)
controller with adjustable parameters, an output power control unit and a high-power output
stage (DC, continuous operation) for resistive ( i.e. heat only) loads with electronic protection
circuits. The power output is short circuit protected, the output power is limited electronically.
Maximal output voltage is approximately 12 V, the current is limited to 1 A.
The system can be connected to the thermistors / heating elements in two ways:
Using separate cables for the sensors and the heating element or
Using the ALA DIN cable assembly that connects both, sensors and heating elements
A large variety of sensors and thermal elements are available (see also
Optional accessories
in chapter 2). Please contact npi for details.
