Especially with the emergence of microprocessors and the continuous improvement of industrial automation technology, load cells have become a necessary device in process control.
From the weight measurement of large tanks and hoppers that could not be weighed before, and the measurement and control of crane scales, automobile scales, etc., to the batching system for mixing and distributing a variety of raw materials, automatic detection in the production process, and control of the powder and granular material feed volume, etc., Have applied the load cell.
At present, load cells are mainly used in various electronic weighing instruments, industrial control fields, online control, installation overload alarms, material testing machines, and other fields, such as electronic truck scales, electronic platform scales, electronic forklifts, dynamic axle load scales, electronic hook scales, etc., Electronic pricing scales, electronic steel scales, electronic rail scales, hopper scales, batching scales, filling scales, etc.
load cell for hopper scales, load cell for industrial use, load cell for automatic detection Zhejiang Nanhua Electronic Technology Co., Ltd , https://www.nhloadcells.com
10 minutes emergency escape breathing apparatus features <br> <br> company's emergency escape breathing apparatus approved by CCS type of product, EC product certification self-contained compressed air breathing protection, only for escape from locations that hazardous gases.
Emergency escape breathing apparatus must not be used for fire fighting, entering anoxic tanks or cargo tanks, or for use by firefighters.
The emergency escape breathing device is equipped with a flameproof hood that covers the head, neck and shoulders. The hood has a clear, wide, bright viewing window.
The operation is simple, open the cylinder valve and put on the hood, without any additional action.
10-minute Emergency Escape Breathers Technical Specifications The 10-minute emergency escape breathing apparatus is a device that provides respiratory protection for people escaping from a hazardous gas environment. It is a self-contained gas cylinder with a storage capacity of more than 400 liters of air, a rated working pressure of 21 megapascals, and a continuous working time of more than 10 minutes. Since the gas is input into the protective cover at a low-pressure constant-current state, it is not necessary for personnel to breathe. Rely on the ambient gas.
1 A mechanical premises shall be equipped according to the number of persons on duty in the premises, one for each person, but not less than two;
2 living spaces with two,
3 There should be another one on board (not including training).
4 Each tank of the tanker should be equipped with one.
EEBD should be avoided in heavy pressure, high temperature baking and low temperature freezing areas. In the machinery space, the EEBD can be placed in the escape route of the central control room, workshop or lower part of the engine room or at the entrance of the stairway; for cargo ships, it can be stored in the fire control station or stairway; the IMOBD should be affixed with the IMO identification mark. And can be identified in the dark.
To periodically check that the EEBD cylinder pressure gauge indicates whether it is within the green zone, it must be replenished when the pressure is below 13.5 MPa.
Gas cylinders are subject to hydrostatic testing every five years.
It should be reminded here that EEBD is a device that provides respiratory protection for persons escaping from a hazardous gas site and should not be used for firefighting and entering cargo tanks or anoxic chambers. In the ship safety inspection, we found that some ships did not have EEBDs as required; some EEBDs in the living areas were locked in the equipment room or large carbon dioxide chambers. Some EEBDs have insufficient pressure on the gas storage or cannot be used due to malfunctions.
The 10-minute emergency escape breathing apparatus is equipped with a flameproof hood that covers the head, neck and shoulders. The hood has a clear, wide, bright viewing window.
