PRO Models

PRO models have value-added technology for demanding optimization and up time requirements of process plants, quality assurance features

and accuracy requirements for EPA compliance, heavy-duty construction for long life in harsh conditions, and highest hazardous area ratings.

Basic models offer a lower price yet still provide essential functions and high quality.

Advanced Features

Device & Process Diagnostics
Device health diagnostics (to NAMUR 107), such as ground and power quality checks, ensure proper installation while process diagnostics

such as real-time signal analysis provide service alerts and insight into process occurrences.

Internal Data & Event Logging
Logging of process values, alarms, EPA self-tests, and events goes beyond record keeping or data redundancy.

It provides added insight for faster decision making and better remote support.

EPA QA and Accuracy
Self-test circuits (zero, upscale/span, linearity and sensor condition), and high precision options enable meeting EPA quality assurance,

and relative mass accuracy specifications in standards such as, but not limited to, ASTM D7392 and EN 15859.

Communications
Certified fieldbus protocols, industrial Ethernet, HART, 4-20mA (to NAMUR 43), USB, and SD cards provide efficient ways to manage devices,

take full advantage of available information, and better control processes.

Heavy-Duty Construction

PRO electronics can operate from -40 °F (-40 °C) to 158 °F (70 °C), and with critical circuits conformal coated, can be installed in dusty

and corrosive environments. All PRO sensing probes are engineered to withstand the rigors of 24/7/365 operation in harsh processes

while not overlooking less known but critical factors, such as flow-induced vibration fatigue

Hazardous Areas

PRO remote control units offer built-in intrinsic safety barriers to directly connect PS Series particulate sensors for intrinsically 

safe installations (all classes/zones/groups). PRO loop powered transmitters with integral electronics

(i.e., one-piece devices) are also available intrinsically safe.
