CHAPTER 1 - GENERAL INFORMATION

1.1 Introduction

Honeywell’s Digital Pressure Sensor with CANopen®, Model
DPS, is an addition to Honeywell’s general-purpose pressure
sensors that are pre-configured with a variety of features and
options for use in a wide range of demanding applications.
Model DPS pressure sensors are a rugged, stainless steel, all­welded devices designed to work with a variety of media, and
built to provide consistent performance in harsh environments.
CANopen

• Connect to longer distance without losing the

• Reduce the wires to be connected

• Take advantage of robust and superior error handling

• Access calibration

• Easily track each device in the network with their

• Update rate of each device connected in the network

Configurations for digital measurements are fully temperature
compensated and calibrated for pressure ranges from 10 psi to
10K psi or 1 bar to 700 bar or 70 kPa to 70000 kPa.

Customers can choose from two different accuracies to meet
their specific application requirements:

• ≤30 psi, ±0.25 %FS

• >30 psi, ±0.1 %FS or ±0.25 %FS

1.3 Features and Benets

( = Competitive Differentiator)

• Wide pressure range [from 10 psi to 10K psi or 1 bar to
700 bar or 70 kPa to 70000 kPa]: Provides support for
many unique applications

 Multiple pressure engineering units (psi, bar and kPa):

Eliminates the customer having to make mathematical
conversions, increasing flexibility and simplifying use

• Rugged design: All-welded, 300 series stainless steel and
Hastelloy
environments

• Accuracy options [ ≤ 30 psi, ±0.25 %FS or >30 psi,
±0.1 %FS or ±0.25 %FS]: Allow customers to select the
accuracy level required for their application

• Output: CANbus with CANopen

• Total Error Band [±2 % FS]: Honeywell specifies Total
Error Band (TEB), the most comprehensive, clear and
meaningful measurement that includes nonlinearity,
repeatability and hysteresis as well as temperature error

• Designed for configurability: A selection of pressure types,
accuracy levels, pressure ranges, pressure connections
and electrical terminations allows customers the ability to
configure the devices to meet their specific application
needs

 Connectors: 5-pin M12, which can be used in industrial

applications, and 6-pin Bendix, which can be used in
transportation applications

2.8 Recommended Grounding

If there is a provision to ground the enclosure at the applica­tion being used, use the recommended grounding method as
shown in Figure 1.

Figure 1. Recommended Shielding Diagram 1

If there is no provision to ground the enclosure in the applica­tion, this shielding method is preferred for wires that run longer.
The shielding of the cable can be connected to CAN_SHLD of
the connector (pin 1 of M12 or Pin A of Bendix) and it can be
grounded at the far end (see Figure 2).
