Period

Canada

An instrument used at the Naval Research Establishment of the Defence Research Board, probably in Halifax, NS. In 1944 the Canadian wartime naval research organization in Halifax was designated HMC Naval Research Establishment; in 1947 it became part of the newly formed Defence Research Board, a government agency formed to conduct defence research & development for the Canadian military. In 1967 NRE was renamed the Defence Research Establishment Atlantic and is now DREA Atlantic under Defence R&D Canada of the Department of National Defence.

Function

An instrument used to record on paper equipment operation times, such as on-off times of an electric motor in a refrigerator for instance..

Technical

Bacharach's Tempscribe is an American made chart recorder of the mid 20th century that could be configured in two different ways to perform two different functions, one being a temperature recorder (see 2004.0123). It also could be used as a recorder used to measure other phenomena than temperature (such as on-off times of a motor) by replacing the temperature sensor with an electromagnet & armature which actuate the pen arm & are themselves actuated by the on-off activity of the test subject to which the instrument is connected.. This example is a Type CT operation recorder for connection in parallel with the load, on either alternating or direct current. One connection is for a 90-220 volt current, the other for a 12-25 volt current. A windup clock controls the rotation of the chart.
