INTRODUCTION
1.1 Introduction
CiDRA Concrete’s SMART hatc h System is the first and only device to
continuously measure and report the air content of fresh concrete in a truck
mixer drum while being transported from batch plant to job site.
This manual covers the basic installation, setup, operation and
maintenance of the SMART
hatc h System.
In all cases, local safety and operating practices take precedence over the
information contained within this document.
1.2 SMARThatch Mobile System, Hardware and Equipment
The SMARThatch System hardware consists of a drum-mounted sensor,
chassis-mounted receiver module, in-cab mounted display, cellular telematics
module, battery charger and associated cables/connectors.
The SMARThatch sensor is mounted to a hatch adapter panel that replaces
the existing drum access hatch as shown in Figure 1. Numerous hatch
adapter panels are available to fit a variety of different truck mixer drum styles.
The SMARThatch sensor is powered by a rechargeable lithium-ion battery
and communicates wirelessly to the SMARThatch receiver module which is
mounted on the back of the truck cab or to the truck frame as shown in Figure
2.
The SMART hatc h in-cab display shows concrete air content (%), concrete
temperature (
°
F or
°
C), drum speed (rpm) and sensor battery charge level (%
remaining) as shown in Figure 3.
The SMART hatc h telematics module uses cellular communication to
transmit measured data to a secure cloud server where it can be accessed
through web-based portal or through an API.
The SMART hatc h battery charger is located inside the truck cab and is
powered by the truck 12 VDC power.
Note: The
SMART hatc h
sensor housing is made of hardened material that is
well suited for the high abrasion environment inside a concrete mixer.
However, to prevent damage that would require sensor replacement, care
must be taken not to strike the face with a jackhammer, chisel, etc.
