Digital Hydraulic Testers Measure Flow, Pressure and Temperature Milwaukee, WI 53235, USA Tel: +1 (414) 769-6400 [email protected] St. Ives, Cambs. PE27 3LZ, UK Tel: +44 (0) 1480 397 400 [email protected] The DHT 2 Series Digital Hydraulic Tester accurately measures flow, pressure, temperature and speed. The testers are designed for testing hydraulic pumps, motors, valves and hydrostatic transmissions. l ACCURATE measurement of flow, pressure, temperature and speed. This easy to use diagnostic unit can pin point hydraulic system faults which reduces downtime and helps with preventive maintenance. The remote flow input can be easily configured by the operator for any LT/ LTR flow block. The calibration is retained in permanent memory. The remote input feature allows main hydraulic circuits and drain leakage flows to be measured simply at the turn of a switch. The tester comprises a turbine flow block and large easy to read digital display which indicates both flow and temperature. Speed and remote flow are selected by switch when required. The flow readout is scaled in lpm, gpm, and US gpm, selected by a push button. Optional accessories for the tester include an infra-red phototachometer and remote flow blocks. l BUILT-IN loading valve. l BI-DIRECTIONAL for unrestricted connection and simplified testing. l INTERNAL oil by-pass protects the tester and system against overpressure. l INPUTS 1 - Flow 1 - Temperature 1 - Speed l LOW power consumption from standard battery. Automatic “Power Off’ feature. l PORTABLE AND LIGHTWEIGHT with angled case for easier viewing and cleaning. l INFRA-RED PHOTOTACHOMETER with ‘On Target’ Indicator. Hydraulic measurement and control

Specifications Model Flow range number Pressure range Fluid temp. range * DHT602/802 has limited pressure control below 86 lpm (23 US gpm). The maximum controllable pressure in this region is calculated by: max pressure (in bar) = 5 x flow (lpm) + 30 ** as per J518 SAE Code 61 standard Functional specification Ambient temperature: Fluid type: Accuracy: Speed range: 5 to 40°C (41-104°F) Hydraulic oil Flow: ± 1% of indicated reading (15 to 100% of range) Pressure: ± 1.6% full scale Temperature: ± 1°C (± 2°F) Speed: ± 0.25% of full scale with one count per revolution 300 - 6000 rpm Construction...
