Deadweight tester
T1300 Terwin Instruments Ltd.

The Terwin model T1300 comparison test pump is a lightweight pressure source that is used to smoothly
generate pressure to test pressure sensors and gauges. The calibration is performed by comparing the
result of a master pressure gauge with the unit which is under test.
The maximum pressure of the T1300 is 1,000 bar (15,000psi) and the operating liquid is standard hydraulic
oil.
The T1300 can be supplied with either a 150mm (6.0") or 250mm (10") diameter pressure gauge with an
accuracy of either ±1% or ±0.25% of full range. 0.25% test gauges are fitted with a mirror dial to prevent
parallax error.
Supplied with the T1300 is an adaptor which has been designed for the Terwin 2000 / 5000 series Extrusion
Pressure transducers / transmitters. The internal threads of the adaptor are ½"‐20UNF‐2B. Other adaptors
are also available.
