Data Sheet

Thermostat Type MBC 8000 and MBC 8100

For heavy-duty marine applications

MBC 8000 and MBC 8100 thermostats designed for use in severe industrial and marine applications where space and reliability are the most important features.

MBC 8100 have all international marine approvals.

The MBC thermostats are designed according to our block design to survive in the harsh conditions known from machine rooms among others.

MBC 8000 and MBC 8100 have high vibration resistance.

Features:

• Compact design

• A high level of enclosure

• Robust and reliable construction

• Resistance to shock and vibration

• Low dierential and high repeatability

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 Figure 2: Setting point correction, while a is the correction factor from the table below.

Figure 2: Setting point correction

Table 5: Correction factor

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

100 − 50

 × 100 %

 × 100 = 50 %

Relative setting:

Factor for setting point deviation Z, see Figure 2: Setting point correction. 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.

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

Figure 3. MBC thermostats with rigid sensor are self-supporting from the sensor pocket. For permissible media

pressure, see Figure 4.

Material specications for sensor pockets:

Sensor pocket, brass

The tube is made of CuZn30, CW 505L acc. to EN 12449, the threaded portion of CuZn39 Pb3, CW 614N acc. to EN

12164.

Sensor pocket, stainless steel 18/8

Material designation X5CrNi18-10, 1.4301 acc. to EN 10088.

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.

Setting

When the top cover screw at the thermostat is removed, the range can be set with the setting screw. The dierential is non-adjustable.
