Shunt calculation
WebHere are step-by-step instructions for shunt calibration of a strain gauge load cell. 1. Connect the transducer to an appropriate strain gauge signal conditioner and allow adequate time for the system to stabilize. 2. Apply a full-scale N.I.S.T. traceable, mechanical input (or load) to the transducer. 3. In electronics, a shunt is a device that creates a low-resistance path for electric current, to allow it to pass around another point in the circuit. The origin of the term is in the verb 'to shunt' meaning to turn away or follow a different path.

WebSep 6, 2024 · Ⅰ Introduction. A shunt is an electrical device that creates a low-resistance route for a current to flow through.This allows the current to flow to a different part of the circuit.Ammeter shunts and current shunt resistors are two terms for shunts.A shunt resistor is used to measure alternating or direct electric current.The voltage drop across … WebNov 16, 2024 · A shunt can be quantified by measuring the flow ratio of the pulmonary cardiac output (Qp) to the systemic cardiac output (Qs). This flow ratio is the Qp/Qs ratio, …

The above equation requires measurement of the end-pulmonary-capillary oxygen content (CcO2) which is difficult to obtain and it is assumed to be equal to the alveolar oxygen content. This is based on the assumption that, if an alveolus is receiving air, then it is perfectly oxygenated.
