Pressure sensors for low pressure (negative differential pressure/ underpressure) ?

I am looking for a suitable pressure sensor for a project involving

a gripping system for composites. With the help of a

compressed air flow and the Coanda Effect a small vacuum is

generated inside the gripper chamber. Therefore, a pressure

sensor that is able to operate in the pressure range from -50kPa

to 0( negative differential pressure), is needed.

Along the Freescale line of products I was able to find the sensors

MP3V5050V and MPXV5050VC6T1. The main difference

between these two models that I was able to notice is the output

range, is there any other differences that I should be aware of?

However, I would like to have information about other suitable

options. The two previous mentioned sensor are of the type

gauge, are there any suitable ones of the type differential? Would

you recommend gauge over differential? What are the main

benefits of each type?

Other features that the sensor should have are:

-Temperature compensated

- Conditioned output Signal ( Amplified Analog Output in Vdc or

digital)

-Operating Temperature Range of 0 to 50 C or above

I thank you in advance for your time and support
