IIoT Sensors for Centrifugal Pump help to pick data on operational parameters such as heat, presence of gas, vapor and more to ensure damage can be prevented.

1. IIoT Sensors
for
Centrifugal
Pumps

2. Introduction
The IoT platform for IIoT integrated smart pumping
solutions comprise of three significant parts:
• Sensors, including cables and junction boxes
• Data collection device
• Monitoring/analysis software

3. Why Sensors?
Sensors are an integral component of IIoT solutions.
• The type of sensor you choose will help your
technology partner customize the solution to your
specific business needs.
• Sensors allow monitoring to be done remotely
without any physical inspection.
• Since Centrifugal pumps owing to the nature of their
operation tend to experience variable flow they have a
greater probability of damage due to overheating and
dry running among other causes.
• Due to this these pumps can face long periods of
downtime. However, with real-time monitoring, it is
possible to provide predictive maintenance to avoid
sudden component failure and eventual downtime.
• Real-time monitoring is possible by attaching relevant
sensors to hardware to pick data about vital
parameters of pump operation.

4. Types of sensors that can be
attached to centrifugal pumps:
• Temperature sensors: Dry running or low flow can result in
rise of internal temperature of the centrifugal pump.
Temperature sensors help detect heating in real time as
well as analyze operational patterns that lead to increase in
temperature. It helps to ensure optimal environment
temperature
• Pressure sensors: Pressure sensors sense pressure and
convert it into an electric signal. Here, the amount depends
upon the level of pressure applied. Since Centrifugal Pumps
rely on liquid for creating flow pressure; these sensors can
detect any deviation from standard pressure range.

5. Types of sensors that can be attached to
centrifugal pumps:
• Water quality sensors: If the pump deals in
pumping water such as in municipal water quality
sensors will help to detect the water quality,
chlorine residue, suspended solids, pH-level and
Ion monitoring among other requirements.
• Chemical sensors: Chemical sensors are ideal for
centrifugal pumps used in Chemical Industry. Their
goal is to indicate changes in liquid or air chemical
changes. Highly corrosive chemicals can lead to
pump leakages causing health hazard.
Further presence of corrosive articles can erode
internal pump components and substantially
reduce pump performance.

6. Types of sensors that can be attached to
centrifugal pumps:
• Gas sensors: Used to monitor changes of air quality and
detect the presence of various gases. Used in
centrifugal pumps to detect presence of toxic or
combustible gas. Hazardous gas monitoring is done in
pumps used for coal mines, Oil & Gas industries,
chemical Laboratory research, Manufacturing – paints,
plastics, rubber, pharmaceutical & petrochemical, etc.
• Smoke sensors: A smoke sensor is a device that senses
smoke (airborne particulates & gases ) and it’s level.
They are especially useful to indicate leakage of
poisonous gases from pumps. They are a good follow up
to temperature sensors or chemical and gas sensors.
• IR sensors: An infrared is used to sense certain
characteristics of its surroundings by either emitting or
detecting infrared radiation. It is also capable of
measuring the heat being emitted by an object. They
can be installed on pumps to gather data about task
competitions.

7. Types of sensors that can be
attached to centrifugal pumps:
• Level sensors: Used to determine the level or amount of
fluids, liquids or other substances that flow in an open or
closed system. They are primarily known for measuring fuel
levels, but they are also used in pumps that work with
liquid materials.
• Magnetic Sensors: A Magnetic sensor or Hall Effect sensor
is a transducer which varies its output voltage in reaction to
a magnetic field. In Centrifugal pumps they can be used to
detect structural wear on impeller blades of centrifugal
pumps.
