User Manual for the
WPS Series Wireless Pressure Sensor
1 INTRODUCTION
1.1 Purpose
This manual describes the Honeywell WPS Series Wireless Pressure Sensor function, operation and maintenance.
1.2 Scope
The manual includes:
• Details of topics that relate uniquely to the Honeywell WPS Series Wireless Pressure Sensor.
• This manual does not cover installation, mounting, or process insertion. See WPS Series Quick Start Guide (document
50095585).
1.3 OneWireless Network Overview
OneWireless is an all digital, serial, two-way communication mesh network that interconnects industrial field sensors to a central sys-
tem.
OneWireless has defined standards to which field devices and operator stations communicate with one another. The communications
protocol is built as an "open system" to allow all field devices and equipment that are built to
into a system, regardless of the device manufacturer. This interoperability of devices using
industry standard for automation systems.
1.4 About the Sensor
The WPS Series Sensor is furnished with an ISA100.11a-compliant wireless interface to operate in a compatible distributed
ISA100.11a wireless system. The sensor will interoperate with any ISA100.11a wireless network.
The sensor includes ISA100.11a-compliant electronics for operating in a 2.4GHz wireless network. It features function block architec-
ture and instantiable input channels.
1.4.1 Power
The sensor is powered by two each, D-sized Lithium Thyonal Chloride cells. Battery life is estimated to be as much as 7.5 years, de-
pending on user settings. There is no external power available for this sensor.
1.4.2 Input
The sensor supports one input channel. This channel is available as either:
• Gauge Pressure
• Absolute Pressure
The sensor measures this analog pressure and transmits a digital output signal proportional to the measured value. Several pipe
thread options are available. See Figure 1 for the functional diagram.
