P3840-PSI Overview

The Fluke P3860-PSI is a Hydraulic Deadweight Tester (DWT) designed to calibrate high-pressure devices. It uses hydraulic pressure, which is generated through a hand pump and intensifier, to calibrate pressure sensing devices like transducers, transmitters, gauges, and pressure switches. The tester includes a tungsten carbide piston and cylinder for long-term stability and durability. The P3860-PSI is specifically part of the P3800 Series of Hydraulic Deadweight Testers offered by Fluke.

P3800 Series Hydraulic Deadweight Testers

With features and options designed to improve accuracy, increase reliability, and simplify operation, the P3800 Series can be used to calibrate virtually any high pressure sensing device including transducers, transmitters, gauges or pressure switches. Three models are available, P3830, P3840 and P3860 offering pressure ranges of 30,000, 40,000 and 60,000 psi respectively (2000, 3000 and 4000 bar). All models are available in two accuracy classes, 0.02% or 0.015% of Reading. The Series P3800 offers an accurate and economical approach to calibrating high pressure devices.

Instrument Base

The base of the instrument encompasses all necessary components for its functioning. It features a high quality hand pump, linked to a 7 to 1 intensifier, which enables the user to effortlessly create high pressure within the system. The inclusion of an oil reservoir allows for the pump’s recharging during the calibration of devices with large volumes. A Test Station is available for linking the Device under Test with the P3800 Series. The instrument’s levelness, crucial for optimal performance, can be ensured by the operator using adjustable feet and a level vial. Additionally, a Piston Float Reference is provided to help the operator identify the perfect “mid float” position for the piston.

Piston/Cylinder

The piston/cylinder is the "heart" of the deadweight tester. P3800 Series pistons are manufactured from tungsten carbide which provides excellent long term stability,

durability, and extremely low coefficients for temperature and pressure.

Weight Sets (Masses)

Standard weight masses are series 3 non-magnetic, austenitic, stainless steel with a density of 7.8 g/cP3. Each mass is marked with the serial number of the instrument and the nominal pressure value. Select either psi, bar or MPa pressure units. PressCal software can be used to support additional pressure units.

Gravity Correction

Gravity varies significantly with geographical locations. Each instrument can be calibrated to local gravity a no additional cost. If unspecified, instruments are calibrated to standard gravity at 980.665 cm/s2.

PressCal Software

PressCal software is a Windows-based software program that allows users to easily apply all necessary corrections (e.g. local gravity, temperature, pressure head, etc.) to enhance the deadweight tester performance. Calibration details are then stored and/or used to automatically create a calibration certificate. The use of PressCal allows for an improved accuracy of 0.008 %. It will permit calibration in any of 12 different pressure units, using the existing weight set.
