Pressure transmitters for any applications
Our transmitter family as unique features as:
- Common intuitive HMI for quick commissioning
- Modular electronics easy to replace
- Reliable sensor technologies
- Easier installation and configuration
- Multivariable version
- Taylor instrument’s All-Welded technology for diaphragm seals
- High long-term stability
- Low cost of ownership
Our pressure products are available with HART / 4-20 mA, PROFIBUS PA, FOUNDATION Fieldbus, MODBUS and WirelessHART communication protocols. Our series allows you to preserve your investment allowing an upgrade from HART to any other available communication protocol in minutes with no need to remove the device from its installation or to reconfigure it. The modular construction of our series allows repairs to be carried out in-field so that the instrument is back in operation few minutes after failure detection.
Temperature and humidity considerations:
High temperatures can have a detrimental effect, potentially causing premature component failure. Exceeding the device’s parameters can have a significant effect on performance.
Low temperatures can cause fill fluids to become more viscous, whilst high temperatures can cause them to vaporise. Variations in ambient temperature and pressure can also have an impact, particularly if the transmitter’s calibrated span is a small proportion of its upper range limit. Atmospheric conditions such as direct sunlight or high winds can cause heating or cooling of transmitters, which can adversely affect their operation. Prolonged exposure to high humidity can also result in corrosion of the transmitter housing and mountings. Transmitter housings are designed to protect electrical components against the ingress of moisture caused by humidity.
Wire, digital or wireless:
For the majority of applications where power is readily available, the two-wire transmitter is often the most practical choice.
Because the current is protected against the effects of changing resistance along the line, signals can be relayed over long distances. Where transmission of accurate data or large volumes of data is essential, the best choice may be to opt for digital transmitters. With wiring and installation costs accounting for almost 50 percent of the total cost of a device, it makes both financial and technological sense to use wireless devices wherever possible.
Wireless devices are used to be largely confined to specialist applications in remote installations, such as water distribution or oil and gas.
The WirelessHART protocol means industry now has an international standard that enables wireless instruments to communicate a wealth of standardised information throughout plant networks.
An electronic instrument is a potential source of electrical energy which in certain conditions can discharged and ignite any accumulated mixtures of flammable gases, combustible dusts and ignitable fibres that may be present.
Various international standards, such as ATEX, FM, IEC, INMETRO, EAC and NEPSI set out various measures for assessing the risk posed by hazardous environments and the steps that need to be taken to minimise the risk of ignition.
For certain applications involving the measurement of gases or fluids subject to rapid density changes, advantages are provided by multivariable pressure transmitter.
This device offers a three-in-one solution for the measurement of flows of liquids, steam or gas with absolute pressure and temperature compensation, ideal for calculating changes in flow density. Incorporating three different forms of measurement into one unit can also significantly reduce installation costs using fewer devices.
Direct and remote seals are used to isolate pressure transmitters from conditions that will shorten their operational life and / or dramatically affect their performance.
As such, they are ideal for a range of pressure measurement applications involving process fluids which operate at extreme temperature and are highly corrosive, dirty, viscous or laden with solids that can block, foul or solidify the impulse lines or the transmitter body. They also present a solution in applications where process wetted materials are required, such as Diaflex, PFA anti-stick and anti-corrosion coatings, or materials for highly corrosive fluids. Remote seal transmitters can also provide an ideal solution for hygienic processes, such as in the pharmaceutical and food & beverage industries, where it may be undesirable to have a pressure measurement device in direct contact with the product.
