Q: What is the primary function of a pressure transmitter?

To convert pressure into an electrical signal — Pressure transmitters measure pressure and output a corresponding electrical signal (e.g., 4-20mA).

Q: Which unit is commonly used to measure pressure?

Pascal (Pa) — The Pascal (Pa) is the SI unit of pressure.

Q: What is a typical output signal range for a pressure transmitter?

All of the above — Common output signals include 4-20mA, 0-10VDC, and 0-5VDC.

Q: What type of pressure measurement is used to measure pressure relative to the atmospheric pressure?

Gauge pressure — Gauge pressure is relative to atmospheric pressure.

Q: What type of pressure transmitter measures the difference between two pressures?

Differential pressure transmitter — Differential pressure transmitters measure the pressure difference between two ports.

Q: Which of the following is NOT a common sensing element used in pressure transmitters?

Thermistor — Thermistors measure temperature, not pressure.

Q: What does 'zero adjustment' refer to in a pressure transmitter?

Setting the output signal to zero pressure when the measured pressure is zero — Zero adjustment sets the output to a specified value at zero input pressure.

Q: What is the purpose of a 'span adjustment' in a pressure transmitter?

Setting the output signal at the upper pressure range limit — Span sets the output value corresponding to the maximum measured pressure.

Q: What type of pressure is measured by a pressure transmitter with a vent to the atmosphere?

Gauge pressure — A vent to the atmosphere measures gauge pressure.

Q: What is the function of the diaphragm in a pressure transmitter?

To sense the pressure and deflect accordingly — The diaphragm deflects proportionally to the applied pressure.

Stainless steel is a durable and corrosion-resistant material.

Question 12 of 15

What does the term 'accuracy' refer to in the context of a pressure transmitter?

Accuracy indicates how closely the transmitter's reading matches the true pressure.

Question 13 of 15

What is the primary function of a 'smart' pressure transmitter?

Smart transmitters offer advanced features like remote setup and troubleshooting via communication protocols.

Question 14 of 15

What is the term for the maximum pressure a transmitter can handle without damage?

Overpressure is the maximum pressure the device can withstand.

Question 15 of 15

In a 4-20 mA output, what current value typically represents the zero pressure reading?

4mA represents the zero pressure reading in the standard 4-20mA output.
