HART Physical Layer Test (2)

"HART Physical Layer Test (1)" describes the first three items: HART waveform test, carrier start/stop and delay time test, and HART signal instantaneous start and stop test.This article goes on to talk about the last six items: output sound test at rest, analog change rate test, input imp

NCS-TT106H Temperature Transmitter Calibration Specifications

Temperature transmitter is used to continuously measure resistance and millivolt voltage signals and convert them into temperature values. NCS-TT106H HART protocol temperature transmitter converts the temperature value into a 4~20mA analog current signal output that is superimposed on the HART digit

How to Choose a Pressure Transmitter at an Intrinsically Safe Explosion-proof Site

In the chemical production process, a considerable number of applications require instruments with explosion-proof functions to meet on-site production safety requirements. Microcyber's pressure transmitter has obtained intrinsic safety and explosion-proof certification and can be used in explos

Basic knowledge of antennas (1)

As an important component for the radiation and reception of wireless signals, antennas play a key role in wireless communications. How exactly does the antenna convert the signal from wired to wireless? What are the key parameters of an antenna, and how to evaluate the performance of an antenna? Th
