    Level Measurement DP type problem

    Hi, apologies for late replying. the transmitter is loop powered no seperate/ external power supply. forcing is accomplished by using HART, yes tx has display

    Level Measurement DP type problem

    - - - Updated - - - The current is unstable, it also fluctuates. The problem persists indefinitely irrespective to any plant conditions. if there was noise problem then the value should have fluctuated when in forced condition.(i think) thanks

    Level Measurement DP type problem

    The erratic behavior means the output is undesirable and unpredictable. Please find attached images **broken link removed** **broken link removed** **broken link removed** **broken link removed** when transmitter is forced to a fixed value it behaves normally as required, this ensures there...

    Level Measurement DP type problem

    Hi, We are using diaphragm type Differential Pressure transmitters for level measurement of different vessels. Each vessel consists of two transmitters one with PLC loop (HIMA with current isolator card CS4/420) {let name it A} and other with DCS loop {let name it B}. The transmitter A show...

    AC main voltage measurement

    no nothing different...... really i became sick of this i also tried to measure ac by dropping it by voltage divider then i increased its level to 2.5V ..... in this case i am able to take samples after 0.444 ms (in proteus) and for 50 hz wave the time for one cycle would be 20ms and no of...

    AC main voltage measurement

    i have placed bridge rectifier at ac mains and use voltage divider of 1M and 10k to drop the voltages at the output i have used voltage follwer opamp circuit. at the output of voltage follower i have placed 10k resistor in series and capacitor in parallel of 10uf. i have set the oscilloscope to...
