Process transmitters

High measurement accuracy with process transmitters

Process transmitters differentiate themselves from pressure sensors through their increased range of functionality: They feature integrated displays, offer high measuring accuracies, freely scalable measuring ranges, communicate via digital bus signals and can be delivered with many case styles and worldwide hazardous area approvals. Through connection to diaphragm seals, WIKA process transmitters are also suitable for the harshest operating conditions.
FAQ
FAQ

Can pressure transmitters work without a power supply?

No. Because pressure transmitters communicate via digital bus signals, they require DC voltage. However, mechanical pressure switches do not require a power supply.

What are the signalling values in accordance with NAMUR?

NAMUR Downscale: 3.5 mA

NAMUR Upscale: 21.5 mA
