Flow Level Pressure
Ralston Instruments Expanded line of DP Transmitter and Valve Bleeder Screw Adapters
Dec 18 2017 Read 747 Times
Differential Pressure or DP pressure transmitters are used in almost every process industry to measure the flow of gas and liquids. It is important to keep them calibrated and one of the biggest difficulties people have in calibrating DP pressure transmitters is connecting a presure calibrator and pressure source without removing the transmitter from service. All DP transmitters are mounted to a block and bleed valve or a 3 or 5 valve manifold that allows the operator to equalise, vent and isolate the transmitter from the process. Ralston Instruments has expanded it's line of DP pressure transmitter adapters to fit an even larger number of manufacturers' block and bleed valves and manifolds.
The DP transmitter adapters fit the following 3 and 5 valve manifolds: Rosemount 2051, 3051 Series DP Pressure Transmitters, Yokogawa EJ series DP Pressure Transmitters, Endress + Hauser Deltabar PMD55 and PMD75 Transmitters, Honeywell Smartline ST700 and ST800 Pressure Transmitters.
Additionally they have also added several bleeder screw adapters for Rosemount, NOSHOK and PGI block and bleed valves that connect pressure transmitters to the process. These adapters thread into the block and bleed valve where the bleeder screw normally goes. They can then be used to pressurise a transmitter for calibration and testing after it has been isolated from the process. The Ralston Instruments bleeder screw adapters fit the following valves: Rosemount 306 In-line manifold adapters, Rosemount Andersoon Greenwood M25 and M251 Block and Bleed gauge valve adapters, Noshok 600 Series, 700 Series, 2070 Series, 2170 Series Block and bleed valve adapters, Parker PGI V-526 and V-527 Bleeder Screw Gauge Valve adapters.
