1. INTRODUCTION
1.1. DESCRIPTION
The MicroTrans
EQ
Signal Processor employs current state-of-the-art digital microprocessor technology
to produce highly stable and accurate differential pressure and air flow measurements. The
MicroTrans
EQ
is factory configured and calibrated to the exact specification determined at time of order.
Simple field configuration of engineering units, operating range, process noise filtering, alarm set points,
etc., are performed via password protected intuitive menus that are accessed through the integral six
button touch pad. Device monitoring and configuration can also be performed by a building
management system through a LonWorks®, BACnet®-MS/TP Master, or Modbus® Slave
communication network. Optional features include AutoZero; High/Low Remote Alarms; Temperature
Compensation; and LonWorks®, BACnet®-MS/TP Master, and Modbus® Slave communication.
1.2. BASIC
OPERATION
The transducer receives a differential pressure signal from the pressure or flow sensing element. This
signal is scaled and linearized before being displayed and transmitted out as a 4-20mA, 0-5VDC, or 0-
10VDC signal.
The AutoZero option detects and corrects any zero offset caused by large ambient temperature changes.
The Temperature Compensation option compensates the flow and velocity signal for density changes
caused by variations in the process air temperature. An external temperature transmitter or input signal
from the building management system is required.
