Pump pressure sensors provide protection for normal operation of the pump

Volumetric pump specialists ROBBINS & MYERS have introduced a non-intrusive pressure sensor that protects the pump under dry operating conditions and under high pressure conditions. Designed to fit at the pump outlet, the RM pressure sensor is considered to be the most effective way to prevent the pump from interfering with operation, as opposed to other conventional 'presence / disappearance' detectors, stator temperature probes and other jamming devices. At the same time, positive displacement pumps are considered as one of the most versatile pump designs with the following advantages: They handle abrasive fluids with minimal wear; accurately measure viscous liquids; and deliver extremely sensitive products with major limitations (Just like most pump products) are run dry. However, using RM pressure sensors is one of the most effective ways for users to protect their positive displacement pumps or other processing equipment during dry operating conditions or high / low pressure conditions. The device consists of sensors, pressure switches and control box composed of three basic components. The sensor is mounted between two standard ANSI flanges to allow fluid flow to be unobstructed. Pressure detection throughout the piping system ensures that the enclosure, fixture, or jumper does not affect the pressure reading. A further feature is the presence of a liquid-filled manometer that visualizes the pressure throughout the pump system.

300mm Diameter Dome Lens

Our Dome Lens is an optical window composed of two parallel curved surfaces. Dome lenses are commonly used in meteorology applications, pyranometers, defence applications and often used in high pressure viewports in underwater cameras and submersibles.For this reason our dome offer both high transmission as well as durability. Other application for our dome include visible-range domes for pyranometers and infrared-range domes for pyrgeometers, and as high pressure viewports in underwater cameras and submersibles.

BK7 or K9L domes are used primarily in meteorology applications. BK7 offers excellent transmission from 300nm up to 2µm. BK7 is a relatively hard material, with excellent chemical durability.
UV fused silica domes ( JGS1 ): For applications operating in the deeper UV range, we offers a range of UV fused silica domes. Fused silica domes are commonly used in underwater applications at extremely high pressures.
Sapphire domes: For infrared applications we can provide sapphire domes. Sapphire is an extremely hard material with transmission of over 80% in the 2-5µm wavelength range. As with fused silica, sapphire is able to withstand extreme pressures, making it the perfect material for underwater camera and missile fairing applications.
