FAQ

What distinguishes a pressure transmitter from a pressure sensor?

A pressure transmitter has circuits for signal conditioning that changes the output of a sensor into standard signals that can be used with industrial control systems. Sensors give you raw measurement data, and transmitters send out standardized, boosted signals that can be sent over long distances and directly connect to control equipment. Because of this difference, transmitters are better for business uses that need accurate and reliable measurement data.

How often should pressure transmitters be calibrated in industrial applications?

How often you need to calibrate relies on how important the application is, the surroundings, and government rules. For safety-critical uses, verification may need to happen every month, but for regular process tracking, yearly calibration cycles may be enough. Changes in temperature, shaking, and toxic conditions in the environment can speed up drift rates, which means that calibration checks need to be done more often.

Are pressure transmitters suitable for hazardous environments?

A lot of pressure transmitters get approvals for use in dangerous areas, such as approvals to be explosion-proof and fundamentally safe. These special tools are made to meet strict safety standards so they can be used in places where dangerous gases or vapors may be present.
