TECHNICAL SPECIFICATIONS

use of in the Dead Weight Pressure Gauge Tester.

The main components of a Dead Weight Pressure Gauge Tester are:

Screw Pump to generate pressure in the circuit. Of adequate capacity and operated by turning the spoked handle. Permits easy and accurate setting of pressure.

Free Piston Assembly of special steel, hardened, tempered, ground and lapped to accurate size and very fine surface finish to provide true floating action.

Set of Weights directly marked in convenient values of pressure and easily stacked on the carrier weight. Available in either/and kgf/cm2, bar Cbf/in² units. Other units on request. Storage box provided. Incremental weights to provide smaller steps available at extra cost for all models mentioned below.

Gauge Connector of 1/2" BSP (female) union for connecting gauge to be tested. Other sizes of gauges can be connected by using adaptors.

Baseplate of sturdy construction provided with legs and levelling screws. The entire circuit is protected by a Sheet Metal Cover.

Models of DW 30 series are provided with 2 free piston assemblies for giving Low Pressure range with smaller steps and High Pressure range with larger steps in a single instrument with substantial cost saving. The ratio of areas of LP and HP Free Pistons is generally 10: 1. Ratio of 5: 1 or 20: 1 car also be provided.
 
COMPARISON TEST PUMP FOR PRESSURE

For quick calibration by comparison with Master Gauge. The Master Gauge to be periodically checked on Dead Weight Pressure Pressure Gauge Tester. Two Gauge Connectors are provided for connecting master gauge and gauge to be tested to the same hydraulic pressure. Screw Pump to generate pressure inthe circuit. Permits easy and accurate setting of pressure.

Model DT 55 : For calibration of vacuum gauges and other sensing, transmitting and recording vacuum instruments. The Vacuum Gauge. Tester is a quick and convenient method of calibration free from the disadvantages of using the fragile mercury manometer. The main components of the tester are:

SCREW PUMP to generate the vacuum in the tester conveniently and precisely. Of adequate capacity and operated by turning the spoked handle.

FREE PISTON Assembly of special steel, hardened, tempered, ground and lapped to accurate size and very fine surface finish to provide true floating action. The free piston is suspended vertically downwards from a rigid frame and connected by a pipe to the screw pump. A CARRIER weight is attached to the free piston for taking more weights. VALVE is provided to connect the circuit to the atmosphere and thus check zero ofthe gauge.

GAUGE CONNECTOR of ½" BSP (female) union for connecting gauge to be tested. Other sizes of gauges can be connected by using adaptors.
SET OF WEIGHTS directly marked in convenient values of vacuum and easily stacked on the CARRIER weight. Available in either /and kgf/cm2, mmHg, inHg units. Storage box provided. BASEPLATE of sturdy construction provided with legs and levelling screws
