The 2088 Smart Pressure Transmitter is an economical addition to the pressure transmitter line of instruments. The 2088 is designed with reliability, long-term performance, and maintainability in mind. The 2088 maintains a specification conformance of at least 3δ. The rugged, reliable performance for which Emerson Process Management transmitters are famous, coupled with Smart capabilities, make these transmitters exceptional values.

The 2088 is available in either gauge or absolute pressure in pressure ranges to 4,000 psi (275 bar). It utilizes a solid-state, polysilicon pressure sensor with a choice of either 316L or Hastelloy isolating diaphragms. The low oil fill of this design has very little temperature effect and outstanding accuracy.

Features
The 2088 provides accurate, stable, and reliable pressure measurement in difficult applications. Its small compact design allows it to be directly connected to a process - providing a quick, easy, and cost effective installation.

The 2088 standard process connection is ½ inch NPT but a variety of optional connections are available. Optional connections range from multiple threaded connections to our full line of manifolds and remote diaphragm seals that provide solutions for virtually any connection.

The 2088 also features a fully configurable LCD that displays pressure and diagnostic information. The information displayed is directly from the microprocessor which accounts for its accuracy and reliability.

Overpressure Limits
Range 1: 120 psig max
All other ranges: two times the URL

Zero Elevation and Suppression
Zero can be suppressed between atmosphere for gage transmimtters or 0 psia for absolute transmitters and upper range limit, provided the calibrated span is equal to or greater than the minimum span, and the upper range value does not exceed the upper range limit. For vacuum calibrations, the compound range option is available (Option Code CR)

Compound Range Capability
Select the Compound Range (CR) option for use in negative gage pressure applications. An enhanced sensor is installed in transmitters with the CR option code.

Transmitter Security
Activating the transmitter security function prevents changes tot he transmitter configuration, including local zero and span adjustments. Security is activated by an internal switch.

Failure Mode
If self-diagnostics detect a sensor or microprocessor failure, the analog signal is 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 may be seen in the detailed product documentation.

Mounting Position Effect
Zero shift of up to 1.2 in H2) (0.30 kPa), which can be calibrated out. No span effect

RFI Effect
Less than ±0.25% of upper range limit from 20-1000 MHz at 30 V/m with leads in conduit. Less than ±0.25% of upper range limit from 20-1000 MHz at 10 V/m with unshielded twisted pair (no conduit)

Tagging
The transmitter is tagged, at no charge, in accordance with customer requirements. All tags are stainless steel. The standard tag is permanently attached to the transmitter. Tag character height is 1/8" (0.318 cm). A wired tag is available upon request.

Accessory Block and Bleed Valve (S5 Option)
The Rosemount 306 Integral Manifold is pre-assembled to transmitter and leak checked.
