There are two types of oil pressure guages. The one that has been around the longest, yet is still in use is a mechanical guage. The later developed guage is called an electrical guage, the system for which is comprised of an electro-mechanical sensing unit [commonly refered to as a "sending" unit], and electrical circuit, and an electrically operated guage. On a mechanical gage, oil pressure signal is sent via a small tube to the gage. inside the gage is a hollow curved spring call a Bourdon tube. As pressure increases, it tries to straighten the spring which has a linkage and arm which is connected to a needle which sweeps a calibrated face thus giving you your numbers. On an electric gage system, a voltage source is sent to the gage which passes through a coil which interfaces with a needle arrangement that moves according to the current flowing through the coil. That current is controlled by the sending unit which is screwed into an oil galley in the engine block. There are differant sensing arrangements but the most common is a variable resistor which allows a calibrated amount of current to go to ground, this is calibrated to the gage face and thus you get your numbers.
The fuel gages, the battery gage, the oil pressure gage, and the coolant gage are on the upper instrument cluster?
after market oil pressure gage instalation on a vw bug
Oil pressure sending unit.
monitor and read oil pressure. sending that info to the gage cluster.
You need to remove the oil sending unit and install a oil pressure gage in it's place then start engine and read gage. Iwould tell you were the sending unit is but you did not say what you are working on.

High oil pressure or a faulty oil pressure gauge.
Possible clogged oil galley, filter, defective oil pressure gage, or the use of an oil that is the incorrect weight. Replace the oil filter with a Purolator filter and change the oil. Install 5W-30 oil. If the pressure is still high then you need to have the oil pressure tested with an accurate test gage, to see exactly what it is.
If the oil light is working and is off with engine running, then you have oil pressure. To determine how much pressure, you need a pressure Gage.
Run your engine for awhile, if it seizes up, the pump wasn't working.
its most likely because the oil is low
Is it ecotec or not? if not, the oil pressure switch is located 2 inches to the left of the oil filter on the back of the motor
Gage pressure is the difference between atmospheric pressure and absolute pressure. If you fill your tire to 35 psi as read on a tire gage, this is the gage pressure. The absolute pressure inside the tire is the pressure of the atmosphere (14.7 psi normally at sea level) plus the gage pressure.
oil gage pressure immediately goes high
As a general rule the oil pressure will drop if the rod and or main bearings are worn excessively. Also could be the oil pump.
replace the oil pump or the engine could blow
It means that the oil pressure switch is showing low pressure.
I really have not heard the term oil pump switch. There is an oil pressure switch on some small engines that will shut the engine down if the oil pressure falls below a preset pressure. These are not installed on vehicles for safety reasons. You vehicle however has an oil pressure sending unit that keeps track of the oil pressure and will warn you of low oil pressure with a red light, or by way of a gage, or both.
If a gas has a gage pressure of 156 kPa its absolute pressure is approximately?
The 6.9 oil pressure gage for some reason does not display a good indication of pressure like the 7.3 engines do. I think this problem is more related to the oil pressure sensor and the display gage rather than the actual physical oil pressure. To be certain, you can have a shop check the pressure with a mechanical gage. Higher pressure does not necessarily improve bearing life. All that is required is sufficient pressure to deliver the oil into every engine bearing. 10 or more PSI at idle should do that. Oil pressure will increase as engine speed increases. I have had several trucks with both the 7.3 and the 6.9. The 7.3 trucks always display in the middle to 2/3 range of the oil pressure gage, while the 6.9s tend to display on the lower end of the gage. Some 6.9s barely stay in the "normal" range, often right at the edge of the "N" for normal. I have NEVER had a 6.9 engine fail due to low oil pressure. However, I always check and maintain my oil level right at full, using a diesel formulated oil like Rotella 15W40. *Never* use thin oils like 5W20. That stuff is only for newer gasoline engines. If you are the type to worry about your oil pressure, add1 can of STP. Be very careful not to let any oil get on the alternator or fan belts. It helps to use a funnel and a cover rag on the belts.
The stock oil pressure sensor on a 97 Saturn can be replaced with an oil pressure gauge for poundage info by first unscrewing the existing sensor. The new sensor can then be screwed into place and wiring ran to a suitable pressure gauge.
It is possibly the sending unit or a defective gauge.
your oil pump could be failing
your oil might be too thin
