The tapping machine HD 2040 is a normalized impact noise generator for the measurement of sound insulation of floors according to ISO 140-6, ISO 140-7, ISO 140-8, ASTM E492, and E1007. It has 5 hammers in line driven by a motor controlled by an electronic system, by means of camshaft. The rate of fall of hammer and the frequency of the impact are constantly monitored to ensure compliance with the legislation. LED indicators on the front panel indicate the proper functioning and impact speed of each hammer, detected by an optical sensor. The hammers are made of stainless steel, hardened and dimensionally stable over time. The unit is equipped with support feet with height adjustable rubber base. On the back cover is available a housing for a detachable spacer which can be used to assist the user to set exact 40 mm vertical falling height from the floor. The spacer can be positioned in the housing with a light pressure; pull to remove it. A spirit level on the top cover allows to set the machine in a perfectly horizontal position. The feet will be turned below the base to reduce the size of the packing and easy transport of the machine. The starting and stopping of the machine is via a front panel button or remotely using the supplied remote control. The antenna is screwed to the connector on the top of the unit and it has to be unscrewed to store the unit in its case. Mains power supply 100 - 240 VAC or rechargeable lithium-ion battery housed inside the unit. The charger is built in; the battery recharges automatically when the machine is connected to the mains supply. The aluminium frame reduces the weight of the machine and makes it easily transportable. The inside of the lid of the machine is treated with sound absorbing material.
