Pressure measurement is essential across industrial, environmental and facilities applications, but installation is not always straightforward. In many cases, the biggest challenge is not the sensor itself. It is the cost, complexity and disruption involved in running cables to the measurement point.
This is where wireless pressure transmitters offer a clear advantage. They provide reliable pressure monitoring without the need for complex cabling, making them especially useful for retrofit projects, temporary monitoring, remote assets and difficult-to-access sites.
The IWPT Wireless Pressure Transmitter is designed for these environments, combining calibrated pressure measurement with plug-and-play wireless connectivity, long battery life and high ingress protection.
What is a wireless pressure transmitter?
A wireless pressure transmitter measures pressure at the process point and sends the data wirelessly to a compatible receiver, rather than transmitting the signal through a hardwired cable connection.
This approach helps simplify installation and reduces the need for trenching, containment, conduit or long cable runs. It also gives users more flexibility when monitoring assets in remote, hazardous or awkward locations.
For many sites, wireless pressure monitoring is not just more convenient. It is often the more practical and cost-effective option.
Why choose wireless instead of wired pressure monitoring?
Traditional wired sensors are effective, but they can become expensive when installation conditions are difficult. Cable routing may involve civil works, plant shutdowns, access challenges or added engineering time. In retrofit settings, this can make a simple measurement upgrade unnecessarily costly.
A wireless pressure transmitter helps solve this by reducing installation complexity.
Key benefits include:
- no expensive cable runs
- faster installation
- less disruption to live systems
- easier deployment in remote or awkward locations
- practical for temporary or trial monitoring
- flexible integration with different receiver outputs
For operators looking to reduce install time and costs, wireless pressure sensing can be a very efficient alternative.
A strong fit for difficult and remote installations
The IWPT Wireless Pressure Transmitter is positioned as a cable replacement solution, which makes it especially relevant where wired installation is impractical, disruptive or expensive.
Typical examples include:
- pumping stations
- sewage plants
- water treatment facilities
- boiler rooms
- plant hydraulics
- plant pneumatics
- tank farms
- HVAC systems
- building management systems
- temporary field trials and servicing work
In these applications, the ability to install quickly without major cable infrastructure can be a major operational advantage.
Wireless range and flexible receiver compatibility
One of the key considerations in wireless instrumentation is communication range. The IWPT offers up to 500 metres line-of-sight range, depending on the receiver used. This provides flexibility across a wide variety of installations.
The sensor is compatible with the full range of IWR receivers and supports a plug-and-play pairing approach. It also allows user-selectable transmission update rates, helping users balance responsiveness with power efficiency.
Receiver options include outputs such as:
- analogue
- digital
- RS-232
- RS-485
- Ethernet
- USB
There are also single, five and multi-channel receiver options available, supporting systems with up to 128 channels. This gives users the ability to scale wireless pressure monitoring across a broader installation.
Long battery life reduces maintenance demand
Battery-powered sensors are often judged by how often they need attention. Frequent battery changes can undermine the benefits of wireless deployment, especially in hard-to-reach sites.
The IWPT offers a five-year battery life at a 10-second transmission update rate, making it suitable for long-term monitoring without constant maintenance intervention.
That is an important advantage for:
- remote installations
- exposed outdoor locations
- service contract deployments
- difficult access points
- temporary monitoring setups
In many cases, long battery life is what makes wireless monitoring viable at scale.
Built for liquids, gases and demanding environments
Media compatibility and environmental protection matter just as much as communication performance. The IWPT is suitable for both liquids and gases and uses a piezo-resistive thick film ceramic sensor inside a 316 stainless steel housing.
Key construction features include:
- 316 stainless steel body
- ceramic sensing element
- Viton seals
- IP68 protection
This combination supports use in demanding industrial and environmental environments where sensor durability is essential. It also helps the transmitter handle exposure to wet conditions and challenging process media.
Accuracy still matters in wireless systems
Wireless convenience should not come at the cost of measurement quality. The IWPT is temperature compensated, calibrated and traceable by serial number, helping ensure consistent and dependable readings.
The product page highlights:
- thermal zero shift of less than ±0.04% FS per °C
- typical thermal span shift of less than ±0.02% per °C
This makes the IWPT a useful option where users need both installation flexibility and confidence in measurement performance.
Pressure range flexibility for varied applications
The IWPT covers pressure ranges from -1 to +400 bar gauge, giving it broad application potential across different industrial and utility systems.
This range flexibility supports use in:
- water and wastewater systems
- pneumatic and hydraulic systems
- asset monitoring installations
- plant and process applications
- facilities monitoring
For users managing different assets across a site, this broad range can simplify selection and standardisation.
Why choose the IWPT Wireless Pressure Transmitter?
The IWPT Wireless Pressure Transmitter is a strong option for organisations that need accurate pressure measurement in places where cabling is difficult, expensive or simply not worth the disruption.
Key benefits include:
- up to 500 metre wireless range
- five-year battery life at 10-second updates
- IP68 protection
- compatibility with liquids and gases
- 316 stainless steel housing with ceramic sensor
- plug-and-play pairing with IWR receivers
- analogue, digital and serial receiver output options
- pressure ranges from -1 to +400 bar gauge
For retrofit projects, remote sites and temporary monitoring applications, it offers a practical alternative to conventional wired pressure instrumentation.
