Shunt measuring stationary 75ShSV1
Also, this device can be called: 75ShS V1, 75ShS-V1, 75 ShS V1, 75ShSA1, 75ShS A1, 75ShS-A1, 75 ShS A1.
75ShSV1 shunt measuring stationary interchangeable with a nominal voltage drop of 75 mV is designed to expand the limits of measurement indicating and recording devices DC.
Accuracy class - 0.5.
75SHSV1 shunts are also produced in the performance of T (tropical) category 2 and OM (sea) category 3.
Shunt measuring 75ShSV1 manufactured in the form of a plate of manganin, soldered brazed tips in brass or copper. Lugs are threaded connections for potential clips - screws and holes for current clamps - bolts.
Shunts measuring 75ShSV1:
Maximum permissible relative error of electrical resistance - ±0,5%.
Limits of permissible variation of electrical resistance as a result of the thermoelectric power - ±0,25%.
Limits of additional error electrical resistance caused by the deviation of the ambient temperature for every 10° C - ±0,25%.
Most superheat shunt plates - 150° C.
Overall average lifespan - 15 years.
