231RS Wet-to-Wet, Differential, Multi-Configurable Pressure Transducer with Armored Jacket

The Model 231RS wet-to-wet differential pressure transducer with remote sensors reduces labor, materials, and time. The differential pressure sensors are installed directly into the pipe and electrical connection is made between the remote sensors and the Model 231RS via cables or conduit, reducing labor cost by one-third and the cost of copper to connect the pressure transducer to the pipe.

Setra Model 3550 - Compact Low Pressure OEM Pressure Transducers

The 3550 is perfect for OEMs that need consistent high levels of performance, reliability and stability because of the units small package size with all 316L stainless steel wetted parts at an unbeatable price performance ratio. A wide choice of electrical outputs as well as both electrical and pressure connections means the unit is suitable for most applications without modifications. 

Selecting a low-differential pressure transducer for critical-care ventilation is one of the most important decisions mechanical designers, engineers and architects can make. These transducers perform precise monitoring and contamination control of isolation-room pressures in critical environments. Properly selected and installed, they help prevent the spread of communicable diseases like tuberculosis (TB).

Setra Systems and DENT Instruments Announce Joint Development Partnership

"The Joint Development is part of Setra’s strategy to expand their energy management solutions offering to their current customer base. The project will leverage the technical, engineering and commercial expertise of the two companies to identify opportunities to innovate and provide solutions for the industry’s greatest challenges. 

There are many risks associated with unmonitored humidity levels in buildings. The most significant of which is the health risks posed to the building’s occupants. Sick Building Syndrome can severely affect occupants’ comfort and productivity, but more alarming are some of the respiratory and other health ailments which can arise from unmonitored humidity levels.

Shock & vibration are two potential mechanical problems for pressure transducers.

Shock is a sudden, unexpected impact that transmits energy to a device in a relatively short time interval. For a pressure transducer, that energy passes through the stainless steel up through the housing. Shock may originate from rough transportation and handling, such as by trucks, forklifts and conveyors. Alternately, shock can be caused simply by dropping the transducer on the shop floor or by an assembler slamming a cabinet door adjacent to it. A transducer may not be damaged by a single shock, but can experience fatigue failure with numerous low-level shocks over the course of its life.

Excessively high temperatures are a common source of pressure transducer difficulties.

Like most other electronic equipment, pressure transducers are effected by temperature, shock and vibrations. They consist of numerous components that only function within specified temperature ranges. Transducers exposed to temperatures exceeding those ranges during the assembly process can be adversely affected.

For high line pressure, high differential pressure applications

The pressure difference across an orifice plate, filter, pump, valve, etc. can be sensed with two pressure transducers such as the Model 206. One transducer measures the high side pressure (P₁) while the other measure the low side pressure (P₂). Pressure media can be any liquid or gas compatible with 17-4 pH stainless steel.

Why are industry leaders using remote sensors?

Wet-to-wet differential pressure transducers have undergone several significant design and technological improvements recently. The most dramatic of which is the ability to install these units with remote sensors, rather than with traditional embedded sensing elements. A contractor can now easily install remote sensors directly into the pipes while an electrician makes electrical connections between the remote sensors and the transducer via cables or conduit. For industrial applications, contractors can order plumbing-ready cable versions with up to 30 feet of cable. When the local electrical code requires conduit, typically for projects like schools or municipal buildings, contractors can order units in the conduit version.

There are a variety of current switches and current transducers currently available for use in HVAC applications. Each product provides different features and benefits for that particular job. This post reviews two common types of current switches and a new technology that eliminates the risk of arc flash hazard during installation.
