OneWireless Gauge Reader Series WGR400 Specifications 34-XY-03-37 July 2009
Introduction
The OneWireless Gauge Reader (WGR) is a battery
powered wireless device that is used to monitor analog dial
gauges. The non-invasive WGR mounts to a gauge, and
converts the analog needle position into a digital reading.
The WGR displays the digital reading on an LCD, and
transmits the reading to a Honeywell OneWireless
Multinode or the Application Gateway.
Features Compatible with most circular gauges from 1.5 in – 4.5
in (38 mm – 114 mm) diameter
Large LCD display showing reading, units, bar graph, battery level, and wireless status
Easy, non-invasive installation, with no process down-time or re-qualification
Self powered, with long battery life
Long range reliable wireless communication
High reading accuracy
IP66 rated, chemical-resistant enclosure
Wide operating temperature range
Application
The OneWireless Gauge Reader is used in conjunction with
the Honeywell wireless network access units, OneWireless
Multinodes and the OneWireless Application Gateway to
form a complete end-to-end solution. Up to 1,000 WGRs
can communicate with a single Application Gateway.
The OneWireless Gauge Reader is intended to automate
the monitoring of conventional analog gauges, such as
pressure and temperature gauges. Many of these gauges
are manually monitored infrequently. The WGR provides
automated, more frequent gauge monitoring.
It is a battery powered device intended for sample rates that
range from 1 sample per minute to 1 sample per 18 hours.
The battery powered WGR is not intended to be used in
high update-rate mission-critical closed-loop control
systems.

*Battery Life (@ 1 sample per minute) 2 months
(@ -20C) 4 months -
*Battery Life (@ 1 sample per 5 minutes) 0.5 years
(@ -20C) 1 year -
*Battery Life (@ 1 sample per 15 minutes) 1 year
(@ -20C) 2 years -
*Battery Life (@ 1 sample per 18 hours) 1.5 years
(@ -20C) 3 years -
Internal Battery Voltage 2.2 V 3.0 V 3.3 V
* Expected battery life can be affected by several factors, including specific image capture and processing configuration
settings, as well as security key update rates. For Magnehelic and Photohelic gauge reader models (WGR421, WGR422),
the battery life is impacted by the LED brightness configuration setting, and will typically be 10% lower than the other gauge
reader models.
