Portable case for measuring and controlling.

p0001The invention relates to a suitcase with hinged lid o. The like. For receiving measuring and / or control devices.

p0002Such bags are used by technicians, craftsmen, etc. to external services such as construction sites, contractors o. Like.. Also is a portmanteau known (DE-OS 33 43 068), are packed in the electrical devices that are ready for immediate use without any need unpacking. Furthermore, measuring case known (DE-GM 81 15 124), in which the measurement handy sorted, are loosely inserted and housed securely. With this measure the user a quick removal of instruments should be made ​​possible on the site.

p0003In the field of preventive fire protection are portable, mobile or stationary fire extinguishers or equipment available. For example, portable fire extinguisher, fire engines o be. Like. With powder filling or other media used as an extinguishing agent. Also one knows gas extinguishing systems that work with CO₂ or halons as extinguishing agents. All these systems and equipment must be constantly monitored and checked for proper functioning. These are service engineers traveling to monitor the fire extinguishers or fire extinguishing systems on site and check. The prescribed for the maintenance of fire extinguishers checks are eg in the DIN 14406, Part 4, set. When gas extinguishing systems the gas weights and their pressures have and dry powder devices, the humidity of the powders are controlled to ensure the operational readiness of such devices.

p0004The invention has for its object to provide a portable device that allows the service technician can perform locally the required tests on the fire extinguishers or fire extinguishing systems quickly, safely and accurately the state of the art.

p0005This object is achieved in that the measuring and / or control devices consist of individual electronic devices that are suitable for the maintenance of fire extinguishers for measuring and / or controlling the fire extinguishing agent, and one of the devices, a microcomputer with a measuring amplifier with analog / digital converter, and an input keyboard and a display, and test the individual devices to and controlling devices or systems can be connected.

p0006The service technician can check with this test case, the weights, the gas pressures and moisture contents of the extinguishing agent without multiple testing equipment as test gauge o. The like. Having to carry extensive equipment. These devices had been entrained in a separately established the trolley. All these known extensive testing be replaced by the erf indungsgemäßen test case, the order of preventive fire protection and its inspection shall apply.

p0007The particular advantage of the test case is the fact that, for example, the weights on an electronic weighing system determines and displays very accurate digital in the electrophotographic device Sichen the test case. Even pressure tests in fixed fire suppression systems that use nitrogen bottles or CO₂ bottles can be displayed on these devices in digital test case by simply connecting the test case.

p0008The moisture content of extinguishing powder could previously only be determined with a very inaccurate, optical subjective test. The test kit according to the invention can first be carried out at the customer a powder moisture testing, the result is displayed digitally in the trunk.

p0009Further details of the test kit are characterized in the dependent claims. An embodiment of a test case is illustrated in the drawing and will be described in more detail below. It shows:<ul><li>Fig. 1 shows the case in the closed state,</li><li>FIG. 2 the open suitcase overlooking the individual electronic devices,</li><li>Fig. 3, the panel of the test case.</li></ul>

p0010The test case 1 comprises a housing 2 with a Dek Article 3, and a support member 4 with the closure parts 5 and 6. In the case 2, the electronic parts and covered by a plate tableau 18th The individual units are as follows: The weighing plate 7 with the underlying weighing beams 8, the accumulator 9 which is arranged underneath the weighing platform 7 in addition to the weighing beams eighth With 10 is the digital display (display) with 11 the adapter field, indicated by 12, the keypad with 13 of the printer. The transducer with the corresponding terminal devices are designated 14 for the charging socket, with 15 for the reference sensor for measuring humidity and with 16 for the jack for the humidity sensor. The electronic pressure sensor with cable is indicated by 17th

p0011The keypad 12 has only 6 individual keys, namely for ON / Off, for the start, for the print, for wet measurement (percent F), weighing (grams) and for pressure measurement (bar).

p0012With this large suitcases device the service technician can detect all the functions that are necessary for measuring and controlling the condition of fire extinguishers, and fire extinguishing systems and their fire-extinguishing agents.
