Both pump models are fitted with a lever for flow rate adjustment which can be used to
vary the flow rate between zero and the maximum. The pumps operate perfectly with
liquids up to a viscosity of approx. 150 mm
2
/sec., with increasing viscosity the pump
output decreases rapidly.

3.5 Temperature control and electronics
The units operate with a Pt 100 resistance thermometer for measuring the bath
temperature (T
i
). The bath temperature, all other temperature values and message
signals as well as inputs are indicated as 2 x 16 characters (10 mm high) on a liquid
crystal display (LCD) with background illumination. Input of the setpoint (T
S
) and of all
other parameters is made by using a membrane keypad with 16 keys and the operator
guidance in the LCD display field. All inputs are stored even when the thermostat is
switched off or if the supply fails.
