WP-TRMS true effective value transmitter
At present, most of the current and voltage meters on the market use simple rectification and averaging circuits to measure AC signals, which have sig
Product details
Main features
● Adopting a two-wire international standard current signal output
● Input of arbitrary waveform alternating signal, wide measurement range
● Directly measure 0-500V/0-5A
Measurement Error Comparison Table
Comparison of measurement errors between true effective value method and mean value method:
Peak factor: Kp=Up/Urms
Waveform factor: Kf=Urms/U
For sine waves: Kp=1.414 Kf=1.111
Therefore, Urms=1.111U
Order: Actual value=1.111U; True value=Urms
Then: γ=(actual value - true value)/true value X 100%
Measurement signal:
● AC voltage 0-500V
● AC current 0-5A
Output signal: (4-20) mA DC (two-wire system)
Working voltage: (7.5-36) VDC
Accuracy: 0.2 level
Allowable temperature: (-30~70) ℃
Relative humidity: ≤ 85% RH (no condensation)
