ABSTRACT:
An electronic balance with a housing (1) that can be put under an above-ambient pressure, for example for the purpose of using the balance in a hazardous environment where a risk of explosion exists, has an inlet (21) for a gas, in particular compressed air. The balance also has a horizontal passage through the housing (1) for a force-transmitting rod member (6) that is coupled to the load-hanger element (12) of the balance. The housing (1) has an opening (9) through which the force-transmitting rod member (6) passes in a substantially horizontal direction without making contact; and the opening (9) also forms an outlet for the gas.
