HADP系列 高精度微差壓變送器-德威爾Dwyer
SERIES HADP Differential Pressure Transmitter combines low ranges with exceptional stability, reliability and an outstanding accuracy of ±0.14% FS. All models come with NIST certificates and are available in unidirectional and bi-directional ranges as low as 0 to 0.5" w.c. and 0 to 5 psid. The Series HADP transmitters are extremely stable allowing for use in the most demanding applications.
