IFG de Wit BV - Test and Measuring Equipment for Pressure and TemperatureIFG de Wit BV is a quality and service oriented manufacturer of pressure and temperature tests and measuring equipment for all applications. Since the first De Wit instruments were produced in 1916, our scope of manufacture has increased to include pressure gauges, test gauges, chemical seals, gas actuated thermometers, chart recorders, dead weight testers, mud gauges and pressure test units. In addition, we offer a comprehensive range of pressure transmitters, temperature sensors, digital indicators and related electronic products. We are small enough to allow a rapid response to customer's special requirements (customised dials, special executions, etc.) whilst large enough to deliver on a timely basis. CHART RECORDERSOur 316 SS case mechanical chart recorders have been designed to give a reliable and continued, long term performance with dependable accuracy, primarily for use in the (offshore) oil and gas industry.
We also offer a smaller instrument with a light metal panel mounted case using 163 mm (6") circular charts. This instrument is very popular with OEM customers. DEAD WEIGHT TESTERSThe operation of dead weight testers is based on the principle of balancing known weights against the force produced by an unknown pressure action on a hydraulic piston of known area. When these forces reach equilibrium and balance the unknown pressure equals the total of the weights and piston. De Wit dead weight testers incorporate a built-in pump for generating pressure and can be used for checking spring gauges, calibrating bourdon gauges, recorders, transmitters or other instruments, pressure testing small vessels, and measuring gas pressure with high accuracy.
Portable version with an accuracy of +/- 0.1 % of rated pressure: Pressure ranges from 500 psi up to and including 15,000 psi. Laboratory version with an accuracy of +/- 0.05 % (optional +/- 0.03 %) of rated pressure: Pressure ranges from 500 psi up to and including 20,000 psi, electric motor drive 220 V (optional 110 V). High pressure laboratory dead weight tester with an accuracy of +/- 0.1 % for very high pressures: 25,000 psi, 35,000 psi and 40,000 psi. MUD GAUGESThe De Wit stainless steel Mud Gauge is an own-designed instrument for accurate indication when cementing, fracturing, acidizing or gravel packing. The case is made of a heavy rugged 316 SS construction, designed with a safety factory in excess of normal requirements. The entire bottom is also made of 316 SS. A 2" connection allows direct mounting to any 2" NPT fitting on pump or well head:
PORTABLE PRESSURE TEST UNITThe De Wit portable pressure test unit with hand pump attachment is a self-contained air driven unit to pressurise valves, hoses, piping, vessels etc. It offers a safe and economical alternative to "home-made" test equipment and eliminates the delays that can occur when equipment is sent to external testing services. The output pressure control is achieved by a built-in air pressure regulator. The pump will automatically cease pumping when the pre-set pressure is reached:
