Mounting The Sensor - HBK MCS10 Montageanleitung

measurement results, the nominal (rated) temperature range must be observed. Constant
or very slowly changing temperatures are best.
Temperature gradients in the transducer, which can result from cooling or heating on one
side, have an effect on the zero point of the transducer. A radiation shield and all-round
thermal insulation produce noticeable improvements, but they must not be allowed to set
up a force shunt.
Moisture and corrosion protection
The multicomponent sensor is encapsulated and therefore very insensitive to moisture.
The sensor attains protection class IP67 as per DIN EN 60259. Nevertheless, sensors
must be protected against the long-term effects of exposure to moisture.
The sensor must be protected against aggressive chemicals that could attack it.
Deposits
Dust, dirt and other foreign matter must not be allowed to accumulate sufficiently to
divert some of the measuring force onto the housing, thus distorting the measured value
(force shunt).

Mounting the sensor

Use the internal centering to center the sensor to the customer's own attachment parts
(see Fig. 6.1).
1. Use the positioning pins provided to align the sensor to the top and bottom of the con­
necting flange. It is advisable not to exceed a phase angle error tolerance of ±0.1° for
the elongated holes on the customer's own attachment parts (aligning the axis of the
pins to the axis of the force).
2. Use hexagon socket screws per DIN EN ISO 4762 of property class 8.8, 10.9 or 12.9
(see Tab. 6.1) to connect the flange. The screw length is dependent of the customer's
own attachment parts.
We recommend DIN EN ISO 4762 cylinder head screws, blackened, smooth­headed,
lightly oiled (μ

Part 1, product class A.
3. Fasten all screws with the specified torque (see Tab. 6.1). Fit the screws by tightening
them diagonally in two steps (50% and 100% of the full tightening torque).
