590 Series Differential Pressure Sensor

Item Number 129-370, Rev. DA Page 1 of 3

Product Description

The Series 590 Differential Pressure Sensors

convert differential pressure to a proportional

electronic output signal. They can be used with any

device that accepts a 0 to 10 Vdc or 4 to 20 mA

input.

Caution Notations

CAUTION:

Equipment damage or loss of data

may occur if you do not follow the

procedures as specified.

Required Tools

• Wire strippers

• 1/8-inch flat-blade screwdriver

• 1/4-inch nut driver

Expected Installation Time

20 minutes

Prerequisites

• Select a suitable location for mounting the

sensor.

• Install field wiring, conduit to the sensor

location.

• All wiring must be Class 2 and comply with

National Electric Code (NEC) and local

regulations.

Media Compatibility

590 Series sensors are designed to be used with air

or non-conducting gases.

CAUTION:

Use with liquids or corrosive gases will

damage the unit.

Environment

The operating and compensated temperature limits

are 0°F to 150°F (-18°C to 65°C).

Pressure Fittings

This unit has two factory-installed 1/4-inch OD

pressure fittings for the pressure signal connection

and typically installed with 1/4-inch push-on tubing.

Both the positive (high) pressure port and the

reference (low) pressure port are located on the

front of the unit, labeled HIGH and LOW,

respectively. For best results (shortest response

times), follow these guidelines:

Document No. 129-370 Installation Instructions November 23, 2009 Installation 1. Remove the shroud from the mounting bracket by squeezing the shroud and lifting it straight off (conduit-mount only). 2. Mount the bracket to a wall, cabinet, etc. using self-tapping screws (not provided). Anchors may be required for concrete and cinder block wall mounting. 5.

Document No. 129-370 Installation Instructions November 23, 2009 Calibration The unit is factory-calibrated and should require no field adjustment. Generally, the mounting position will have a zero shift effect on ranges below one inch WC. If possible, any zero and/or span offsets should be corrected by software adjustment in the user's control system. However, both zero and span adjustments are accessible either on the front of the unit or by removing the optional conduit enclosure.
