Answer / hamid

on the vibration probe we start by cheking the resistance of the probe
than we check the linearity using the tk-3

how can be calibrate flow indication transmitter (rosemount) it shows excess milli amps nearly about 24 ma on full scale, but its scale was set on 20ma on full scale..???how can be simiulate..???

Lux meter is the measuring device to measure the lux level of lighting fixture. in industrial sector two types of lighting fixture is being used as street lighting purpose 1. HPSV (Sodium) and 2. HPMV (Mercury). HPMV having white light which is an combination of red, blue and yellow colour, while HPSV haivng Yellow lighting. in HPSV red & blue colour will be absent. during measurement of the lux level of HPSV and HPMV fixture. 1. Lux meter can measure the actual lux level of both fixture? 2. or it will show false reading for HPSV fixture light as it has only yellow light present. please give me answer

A temperature sensor (RTD) connected via a temperature transmitter is adjusted to give an output of 4ma at 60 deg and 20 ma at 600 deg. This output (4-20ma) from the transmitter is connected to an IGBT-inverter to control a high speed (-12,000 to +12,000 RPM) DC motor. And in the inverter it is programmed as, for 4ma the motor speed will be -3,000 RPM and for 20ma the motor speed will be +10,000 RPM. The question is : If the motor speed is +5,500 (RPM), what will be the temperature? (-sign indicates that the motion is in reverse direction).
