Rosemout 2088 Absolute and Gage Pressure Transmitter

                                 Rosemout 2088 Absolute and Gage Pressure Transmitter

Output
Code S: 4–20 mA
Code N: 1–5 Vdc, Low Power
Outputs are directly proportional to the input pressure
Selectable HART

Rosemout 2088 Absolute and Gage Pressure Transmitter
Digital communications based on HART Revision 5 (default) or
Revision 7 (option code HR7) protocol can be selected. The HART
revision can be switched in the field using any HART based
configuration tool or the optional local operator interface (LOI).
Service
Liquid, gas, and vapor applications
Power supply

Rosemout 2088 Absolute and Gage Pressure Transmitter
External power supply required. Transmitter operates on
10.5–42.4 Vdc with no load (5.8-28 V for Low Power). Reverse
polarity protection is standard.
Load limitations
Reverse polarity protection is standard. Maximum loop resistance
is determined by the power supply voltage as described by the
following equations:

Material selection
Emerson Process Management provides a variety of Rosemount product with various product options and configurations including
materials of construction that can be expected to perform well in a wide range of applications. The Rosemount product information
presented is intended as a guide for the purchaser to make an appropriate selection for the application. It is the purchaser’s sole
responsibility to make a careful analysis of all process parameters (such as all chemical components, temperature, pressure, flow
rate, abrasives, contaminants, etc.), when specifying product,materials, options and components for the particular application.
Emerson is not in a position to evaluate or guarantee the compatibility of the process fluid or other process parameters with
the product, options, configuration or materials of construction selected.

Transmitter security
Activating the transmitter security function prevents changes to the transmitter configuration, including local zero and span
adjustments. Security is activated by an internal switch.Failure mode alarm If self-diagnostics detect a sensor or microprocessor failure, the analog signal will be driven either high or low to alert the user. High or low failure mode is user-selectable with a jumper on the
transmitter. The values to which the transmitter drives its output in failure mode depend on whether it is factory-configured to
standard or NAMUR-compliant operation. The values for each are as follows:

This device contains a thin wall diaphragm. Installation,maintenance and use shall take into account the environmental conditions to which the diaphragm will be subjected. The manufacturer’s instructions for installation and maintenance shall be followed in detail to assure safety during its expected lifetime.
2. Flameproof joints are not intended for repair.
3. Non-standard paint options may cause risk from electrostatic discharge. Avoid installations that could cause electrostatic
build-up on painted surfaces, and only clean the painted surfaces with a damp cloth. If paint is ordered through a special option code, contact the manufacturer for more information.
