Description
FlexBar HRT is a loop powered, configurable pressure transmitter. FlexBar HRT is used in food, chemical and petrochemical industries
FlexBar HRT measures the pressure by means of a polysilicon strain to measure absolute or gauge pressure for machine and hydraulic
gauge sensor. The electronics are separated from the media by a thin applications etc.
diaphragm and an oil-filling. Three different oil fillings are available
including a mineral oil complying with demands from FDA for use in The wide range of process connections together with the configurable
the food and pharmaceutical industries. facilities make FlexBar HRT the ideal choice for all pressure measuring
applications.
The electronics are located in a separate sealed housing giving
FlexBar HRT superb resistance to moisture. Cable connection is via Hygienic process connections for a wide range of standards are avail-

14. CombiConnect Hygienic Replaceable Connections
Description
CombiConnect is a series of hygienic, replaceable
connections in acid-proof stainless steel (W1.4404/AISI
316L). The concept fits the G1/2A nipple versions of
FlexBar HRT pressure transmitter and the CombiTemp
Pt100 sensor.
The products comply with the strict demands from the food
industry, represented by organisations such as 3A, FDA
and EHEDG.
It takes less than 2 minutes to mount the pressure
transmitter or Pt100 sensor on the CombiConnect
connection.
CombiConnect is an entirely new concept offering high
flexibility and a low stock. The connection system is the
ideal choice for customers measuring temperature and
pressure in environments with several different
connections.

Hygienic Installations
Measures to be taken at hygienic mounting according to "European Hygienic Equipment Design Group"
1. Avoid blind pockets when connecting two pipe ends.

When the HART® communicator is used for configuration of the FlexBar 3501, the total

In Multi-drop mode up to 15 slaves can be connected to a 2-wire cable.
The transmitters are „parked“ at a fixed output of 4 mA. Each device
must have a unique device number different from 0. In case that one
transmitter is given a device number of 0, the system will revert to
