Maintaining a proper lubrication oil system on maritime vessels is critical to reduce friction on moving parts and avoid overheating. Each ship is different, so that lubrication systems may include any combination of controllers, valves, coolers, transmitters and pumps. No matter what equipment the lubrication oil system contains, it relies on temperature sensors or transducers …
Ralston Quick-connect Adapters Do you find that when testing pressure instruments, connecting everything actually takes the longest time? Do you find that looking for leaks takes longer than doing the actual test!? Will not anymore! If you are connecting to pressure gauges using NPT or BSPP adapter then Ralston Quick-connect Adapters will make your job …

The Volume Controller (QTVC) from Ralston Instruments is the ideal lab tool. Calibrate both very low pressure or high pressure instrumentation using nitrogen with an attached pressure gauges or calibrator. The proprietary pressure balanced fine adjust piston allows for extremely precise, finger-tip control of pressure at 0.03 psi (2 mbar) or 3000psi (210 bar) or …

Archimedes-born in 287 BC – was a practical man and took full advantage of Laws and the repeatable behavior of Physics. He invented a variety of machinery including a screw pumping device that lifted water from a river to irrigate field crops. Today we employ the same laws and engineering to manufacture a variety of …
To start off our discussion of calibration and its importance we should first start with a clear definition. Calibration is a comparison between measurements – one of known magnitude or correctness made or set with one device and another measurement made in as similar a way as possible and with a second device. The device …
