l) Pressure reading stability = ±0.25% of upper range limit for two years.
m) Repeatability = ± 0.1 at max span.
n) Ambient temperature for operation: 55°C.Output stability should be 0.1% over the span within this temperature range.
o) Protection against the following shall be provided and clearly mentioned in the quotation.
iii) Current/voltage transients
iv) Reverse polarity
Any other item required for above protection is to be incorporated alongwith.
p) Flame and explosion proof enclosure suitability to operate in hazardous location class-1, Division -1 and group -C&D. Approval certificate for the above should be given from the competent authority i.e. CCOE/ATEX certification and calibration report shall be enclosed with the offer.
q) A local display should be integral part of the pressure transmitter. For this, digital display/analogue meter in percentage proportional to the range shall be provided.
r) End connections of capillary should be suitably supported.
s) Proper mounting bracket & 'U' Bolt shall be supplied along with each equipment for installation on 2" pipe
