Dwyer Capsuhelic Series 4000 Differential Pressure Gauge, Range 0-4 kPa Dwyer Instruments 4000-4KPA

The Capsuhelic series 4000 differential pressure gauge with an aluminum case has a circular 4" (100 mm) dial, and four female 1/4" NPT rate connections, and measures pressure with single scale in inch water column (WC), mm WC, cm WC, psid, or kPa with a display accuracy of + or - 3 or 4%. The die-cast aluminum case with impregnated hard coating is for measuring air and compatible gases and oil-based liquids. The circular dial is 4" in diameter and measures pressure with a single scale in inch water column (WC), mm WC, cm WC, psid, or kPa. The pressure being measured is held within a capsule in the gauge, which permits the use of the gauge on system pressures of up to 500 psig, even with differentials less than 0.1 in WC. The gauge accuracy is + or - 3% of full scale at 70 degrees F (21.1 degrees C) with + or - 4% of full scale on some models. The pressure limits are -20" Hg. to 500 psig. The temperature limit is 20 to 200 degrees F (-6.67 to 93.3 degrees C). Four female connections with 1/4" NPT (National Pipe Thread) rate provide for vertical mounting of the gauge. The connections are paired with one high and low pressure pair of taps on top for air and gas and one high and low pressure pair on bottom for liquids. This gauge is suitable as a readout device when measuring flowing fluids, pressure drop across filters, liquid levels in storage tanks, and other applications involving pressure, vacuum, or differential pressure. The gauge comes with two 1/4" NPT plugs for duplicate pressure taps, four flush mounting adapters with screws, and four surface mounting screws.

Pressure gauges are instruments used to measure the pressure of a gas or liquid inside a vessel and, often, to help ensure the optimal amount of pressure for a given application. Pressure gauges can range from everyday instruments, such as those used to measure the air pressure in a car or bicycle tire, to highly accurate gauges used in mechanical and industrial processing. Most often, pressure gauges measure pressure relative to another reference. For instance, gauge pressure measures pressure relative to ambient air. An example of a pressure gauge measuring relative to ambient air is a tire pressure gauge or a blood pressure gauge. Differential pressure is the difference in pressure between two points, such as when measuring liquid flow along various points in a pipeline. An absolute pressure gauge measures pressure relative to a perfect vacuum, such as an atmospheric or barometric pressure gauge. All types of pressure gauges include either a male or a female mount to connect to the vessel where pressure is being measured, and display results on a dial with varying increments of measure across a given range.

Instruments manufactures measurement and control instruments, including pressure gauges, flow meters, level instrumentation, temperature instrumentation, and air quality monitors. The company, founded in 1931, is headquartered in Michigan City, IN.

uk police have declared the blast outside a hospital in liverpool a terrorist incident and said they believed the explosion occurred when a man brought an improvised device into a taxi.

officers said monday that a passenger is believed to have entered the vehicle with an explosive device that suddenly went off. the suspect died in the blast but the taxi driver managed to escape. police have arrested four men, all aged in their 20s, and believe they know the identity of the suspect.

home secretary priti patel said monday that the uk’s terror level had been raised from “substantial” to “severe” following the explosion, pa media reported, meaning an attack is “highly likely.” patel noted that the blast marked britain’s second terrorist incident in a month, following the murder of lawmaker david amess in october.

sunday’s incident began when the driver of the taxi picked up a fare on a residential street in the northwest english city. a man entered and asked to be taken to liverpool women’s hospital, a short drive away, assistant chief constable russ jackson of counter terrorism north west said at a press conference on monday.

“our enquiries indicate that an improvised explosive device has been manufactured and our assumption so far is that this was built by the passenger in the taxi,” jackson said.

surveillance camera footage appears to show the taxi slowing to a stop in the hospital’s car park a few minutes later, before a sudden blast takes place. a man is seen leaving the car before it is quickly engulfed in flames.

the hospital specializes in a range of women’s healthcare fields, including midwifery and postnatal care, gynecology and terminations of pregnancy. it delivers around 8,500 babies and performs 10,000 gynecological procedures each year, according to its website.
police said the motivation for the incident is unclear, and did not confirm that the hospital was the target. jackson said police were “aware” of a nearby remembrance sunday event commemorating britain’s war dead.
services around the uk held a two-minute silence at 11 a.m. local time on sunday, moments after the explosion occurred. “we cannot at this time draw any connection with this. but it is a line of inquiry which we are pursuing,” jackson said.
he confirmed that two addresses were searched in the city following the explosion, and “significant items have been found” by officers.
three men — aged aged 29, 26 and 21 — were arrested at one address, and a fourth man, aged 20, was later detained.
the driver of the cab has been praised by boris johnson for preventing a larger blast, with the prime minister saying monday that “it does look as though the taxi driver in question did behave with incredible presence of mind and bravery,” according to pa media.
liverpool’s mayor joanne anderson added to the bbc on monday: “what an awful experience, and jumping out of the taxi, he’s lucky to have escaped.
anderson said the incident could have been far worse. “it doesn’t bear thinking about, and what a heroic effort from the taxi driver,” she said, praising his “quick thinking to lock the taxi and get out of the taxi.”
