This is a simple temperature measurement probe circuit. This circuit measures temperature either on a PC board or at the probe tip to which contains the temperature sensor. It can be used for debugging and troubleshooting electronic circuits. Here is the schematic diagram of the circuit: This circuit uses the MAX6610 as temperature sensor. We can scale the output to […]

This circuit is used to allow a 4mA–20mA to power an analog temperature sensor. To provide a 4mA–20mA output over a 3.75V–28V compliance range this circuit uses an op-amp, low-dropout linear regulator, transistor and an analog temperature sensor. It is powered by the loop with the only consequence being a slight offset error because of the quiescent current of the […]

This is a circuit that can be used to meter the capacitance. This circuit is similar to previous meter circuit. It has a little difference, this circuit uses transistors rather than logic gates. Here is the circuit: This circuit uses pnp transistor. if we can’t find exact type as shown in the circuit, we can use almost any pnp transistor […]

LTC6101 op-amp can be used to build High voltage current monitoring/sensing. This circuit can senses current in 500 volts system. Here is the schematic diagram of the circuit: To hold off the voltage, two external Mosfets is added to the circuit. It will allow to connect LTC6101 to very high potentials and measure the current flow. At Rsense, the output […]
