Example

A MBC 8100 with capillary tube length 2 m and

range 50 – 100 °C must cut out at 75 °C in 70 °C

ambient temperature. At which cut out

temperature should this temperature control be

set at in 20 °C ambient temperature?

The relative setting Z can be calculated from the

following formula:

Setting value min. range

max. range - min. range

Relative setting: 75 - 50

x 100 = 50%

100 - 50

Relative setting:

Factor for setting point deviation Z (g. 1).

Z - 1.2

Correction factor a (table under g. 1) a = 2.2

Setting point correction Z x a = 1.2. x 2.2 = 2.6 °C

The MBC must be set at 75 + 2.6 = 77.6 °C in

20 °C ambient temperature in order to cut out

at 75 °C ambient temperature.

Setting point correction The sensor on MBC 8100 thermostat contains

an adsorption charge. Therefore its function

is not aected whether the sensor is placed

warmer or colder than the remaining part of

the thermostatic element (bellows and capillary

tube). However, such a charge is to some extent

sensitive to changes in the temperature of

the bellows and capillary tube. Under normal

conditions this is of no importance, but if the

thermostat is to be used in extreme ambient

temperatures the setting point might change.

The deviation can be compensated for as follows:

Setting point correction = Z x a

Z can be found from g. 1, while a is the

correction factor from the table below.

Installation Installation

MBC thermostats are designed to withstand the

shocks that occur, e.g. in ships, on compressors

and in large machine installations. MBC

thermostats with remote sensor are tted with 5

mm screws to bulkheads or similar. See g. 2

MBC thermostats with rigid sensor are

self-supporting from the sensor pocket.

For permissible media pressure see g. 3.

Sensor position

As far as possible the sensor should be positioned

so that its longitudinal axis is at right angles to

the direction of ow. The active part of the sensor

is ø13 mm x 50 mm long on thermostat with rigid

sensors and 2 m capillary tube.
