which type of output is suitable: analog voltage, analog current, and digital (HART or MODBUS communications)?

When select pressure sensors, you need to decide which type of output is suitable for your application: analog voltage, analog current, and digital (HART or MODBUS communications)? 

Analog voltage output: 3-wire electrical connection, poor anti-interference ability, suitable for short-distance transmission.
Analog current output: 2-wire electrical connection, suitable for long-distance signal transmission.

Digital output: can be connected with digital systems and offers greater flexibility in terms of signal processing. 

We have pressure sensors with analog output and digital output for you to choose, like our UPB13 high cost-effective pressure transmitter, UIB5 intelligent pressure transmitter with HART etc.
