Pressure Gauges
Pressure Sensors for Hydraulic Systems: Range, Protection and Wiring
Quick answer: choose a hydraulic pressure sensor with a range at least 1.5 times the normal working pressure, an overpressure rating we...
Vacuum Gauges and Digital Vacuum Gauges: Scales, Units and How to Choose
Quick answer: a vacuum gauge measures pressure below atmospheric pressure. On an ordinary gauge the vacuum scale runs from 0 down to -1...
4-20 mA Pressure Transmitters: Wiring, Scaling and Calibration Explained
Quick answer: a 4 to 20 mA pressure transmitter sends a current between 4 mA (bottom of the range) and 20 mA (top of the range) through...
Pressure Transducer vs Transmitter vs Sensor: Which Do You Need?
Quick answer: a pressure sensor is the sensing element that reacts to pressure. A pressure transducer turns that reaction into an elect...
Load Cell vs Pressure Sensor: When to Weigh and When to Measure Pressure
A load cell measures force or weight directly, while a pressure sensor or gauge measures the pressure of a fluid or gas. They can often...
How to Choose a Load Cell or Pressure Gauge Supplier: A 12-Point Quality Checklist
To choose a good load cell or pressure gauge supplier, check six things: do they give you the maker’s full datasheet, can they sh...
Best Pressure Gauge Manufacturers: Who Makes Them and How to Choose
The best-known pressure gauge makers include WIKA (Germany, founded 1946), Ashcroft (US, a Bourdon gauge maker with more than 150 years...
Analogue vs Digital Pressure Gauges Compared: Eight Real Models Side by Side
Analogue (Bourdon tube) pressure gauges win on simplicity, toughness and cost, with no battery to flatten and a pointer that anyone can...
Pressure Gauge Accuracy Compared: What 2.5% vs 0.025% Means in Real Numbers
Pressure gauge accuracy is expressed as a percentage of the gauge’s full range, so the same “2.5%” or “0.25%&rd...
Gas and LPG Pressure Gauges: Low Pressure Capsule and Bourdon Types
For low pressure gas work, the key is a gauge with a very low range and enough sensitivity to read a few kilopascals, such as a capsule...
