7 title: Honeywell mprls0025pa pressure sensor
13 Honeywell pressure sensor of model mprls0025pa.
18 There are many models with different pressure ranges available. The vendor
20 differ in the pressure range, unit and transfer function.
22 To support different models one need to specify the pressure range as well as
23 the transfer function. Pressure range needs to be converted from its unit to
27 sensor. The minimal range value stands for the minimum pressure and the
28 maximum value also for the maximum pressure with linear relation inside the
