SENSOR MODELS
Offered in three different models, EchoPro® is an intrinsically safe, two-wire, pulse radar level sensor that
provides a continuous 4-20 mA current output that’s proportional to the media level in a tank or sump. Make
sure that the model purchased is appropriate for your application.

OPERATING PRINCIPLE
The sensor emits a microwave pulse from its antenna, which travels at the speed of light to the surface of the
medium below. A portion of that energy reflects off the medium and returns to the antenna. The time gap
between energy emission and receipt is called the “time of flight”, and is proportional to the distance between
the medium surface and the sensors measurement location, as at the bottom of the antenna. The sensor
measures the time of flight and translates this value into a continuous 4-20mA signal output that’s
proportionate to level within a defined measurement span.
FEATURES
Easy configuration with LCD push button display module
Adjustable loop fail-safe, no change, 20.5 mA, 22 mA
Small 12” (30.48cm) dead band enables full tank measurement
Recognition, storage and deletion of false echo signal returns
BENEFITS
Unaffected by physical process and environmental conditions
Ideal for applications with higher temp, pressure, foam, vapor and vacuum
Strong signal penetrability with minimal attenuation over distance
LIMITATIONS (FACTORS THAT COULD INFLUENCE PERFORMANCE)
Air particulates with a high dielectric constant value such as lead or ferroalloy
Highly dense air particulates that attenuate microwave emission and receipt
Material build-up on the antenna that degrades microwave emission and receipt
Mediums that have an extremely low dielectric constant value with little reflectivity

Part 15.256, Class B: LR36 (3”, 4”, 5” horn), LR41 (3”, 4”, 5” horn) & LR46 (8”,
10” parabolic) series can be installed on any tank material.
Compliance: The equipment complies with the following standards:
IEC: 60079-0:2011 & 60079-11:2011
EN: 60079-0:2012 & 60079-11:2012
RoHS
This product is an intrinsically safe version (Ex ia IIC T6…T3 Ga) with stainless steel
housing. All electric circuits are fully encapsulated in the internal enclosure, where no
conductive parts will contact with flammable gas. Two-Wire system in service, the
power of the product is from safety barrier limited at:
Ui = 26.4V Ii = 114mA Pi = 0.752W Ci = 0 Li = 51µH
A safety barrier should be placed between power source and instrument for intrinsically
safe version. All connection cables must be screened with maximum length of 500m
(stray capacitor ≤ 0.1 µF/Km and stray inductance ≤ 1mH/Km). The level measurement
instrument must be connected to ground potential and unapproved supplemental
devices are not allowed to use.

Cable Connection:
This product shall be used with certified IECEx and ATEX cable glands and block plugs. The cable
used for “ia” terminal shall be in compliance with the requirement of EN/IEC 60071-14 clause.
Additional requirements for types of protection “I” – intrinsic safety. It’s installing and operation
instructions should be observed if other cable glands are used.
Care should be taken with the cable glands which should be matched to the cable used outside
diameter property; see mark of cable gland for the outer diameter of being cable used.
In order to ensure the required minimum degree of protection, the bolts of cable glands, blanking plug
and relevant sealing bolts are to be tighten down.
