Selecting a Sensor: MiningShock and VibrationShock and vibration can eat away at a pressure transmitter. Having a sensor that cannot withstand these forces could lead to unnecessary downtime.

Electrical InterferenceEMI/RFI interference on a mining site, or on any site, can cause signal instability and inaccuracy in the pressure transmitter.

True Cost of Failure: Construction

Pressure transmitters help indicate that the application is within safe operating parameters.


In addition to personal injury costs, an accident affects production. These indirect costs can include schedule delays, repairs to damaged property, maintaining insurance coverage, and added administrative time, not to mention losing the trust of your mostvaluable customers.

Selecting a Sensor: ConstructionLong-Term StabilityThe performance of a transmitter on day one is obviously essential, but its performance in year two, three and beyond is even more important.

Shock and VibrationIs this a pressure transmitter that is going to be able to withstand the shocks and vibrations that are commonly present in a construction site? What about internal stresses such as changing loads and cavitation?

Pressure SpikesYou can have huge pressure spikes when you open and

propagated waves of pressure that come back and hit the pressure sensor. Your sensor needs to be able to withstand these variations.

Survive the EnvironmentYou need a pressure sensor that can survive the environment in which your equipment is used. If your unit is unable to withstand the elements—such as torrential rainfall—then water will get into the sensor. This may disrupt the electronics and skew the output.

Sensors are at the heart of your monitoring device.

While others may outsource this function to avoid the millions in capital expenditures, we refuse to relinquish control of something so important.

By manufacturing our own sensors, we help decrease defect rates and improve durability and quality.

We Do Things DifferentlyWe believe that all relevant processes and technologies must be under our control. For instance, we make our own sensors to ensure we deliver reliable products.

We Make It WIKA Tough...So You Never Have To Say You’re Sorry.

No one want to receive a phone call from a customer with a machine down. So, why chose a sensor from a general industrial catalog when you have a mission-critical application?
