we r going to bid for a transmitter tender,and now selected the models of FUJI,but there is one doubt about the selection. The customer asked for one DP transmitter of (range 0-2.71KPa,maximum S.P. 16MPa), right now we chosen FKC 22(span 0.1-6KPa,MSP. 10MPa),but the MSP. cann't match the required MSP.16MPa.
So we want to know wheahter we can use FKC 33(span 0.32-32KPa),the MSP is 16MPa, can satisfy the MSP. requirement of customer.
According to the specification of FKC transmitter,if we adopt FKC 33 for the use of 0-2.71 range, the accuracy would be influenced.
but how many would the accuracy be influenced? The original accuracy is 0.065%(the precondition is the selected span should exceed 1/10 of maximun span,otherwise the accuracy would be degraded).
based on the formula in the specification, I have counted the accuracy of FKC 33 which is used for 0-2.71KPa range, it would be 0.075%. Does it mean the accuracy is 0.075% of 2.71KPa? or 0.075%of 32KPa?
and I have some doubts on the following items.
1). how many is 1/10 of URL for Model "FKC 33"?
3.2KPa? or 0.32+(3.2-0.32)/10?
2)how to understand "Remark: To minimize environmental influence, span should be greater
than 1/40 of the max. span in most applications."
Does it mean we can use the transmitter which span is greater than 1/40? We know the accuracy would be influenced,if the selected span is between 1/40-1/10 of URL.
Your prompt help would be very appreciated. thanks.
