CLEVELAND CONTROLS

Cleveland Controls is a manufacturer of pressure sensing and control devices for HVAC, combustion, and industrial air systems. The company's product line includes static pressure probes, differential pressure switches, air pressure switches, and related accessories. These devices are used to measure and monitor air pressure in ducts, plenums, and air-handling systems, and to initiate control actions based on pressure thresholds. Cleveland Controls products are commonly found in building automation, combustion safety, and industrial ventilation applications. 3G Electric supplies Cleveland Controls static pressure probes and other pressure sensing products to customers worldwide. The probes we stock are available in a range of configurations to suit different duct sizes and connection requirements. For example, the static pressure probes we carry have insertion lengths from 1 1/2 inches to 8 inches, and process connections that are either smooth or barbed. Smooth connections are typically used with push-on tubing, while barbed connections include a metal barbed hose adapter for secure attachment to flexible tubing. The probes are constructed with a metal body and are designed for installation through duct walls. The exterior length of the probes we stock ranges from 1 1/4 inches to 1 3/4 inches, which determines how far the probe extends outside the duct. The overall length varies from 3 1/4 inches to 9 1/4 inches, depending on the insertion length and connection type. These probes are passive devices that provide a pressure signal to a pressure switch, transmitter, or gauge. They are not electrically powered and contain no moving parts. The static pressure probes are used in applications such as monitoring filter differential pressure, proving airflow in duct systems, and sensing pressure in clean rooms and laboratories. Cleveland Controls also manufactures pressure switches that can be used with these probes to control fans, dampers, and other equipment. 3G Electric supports the Cleveland Controls line by stocking a selection of static pressure probes and offering them for global shipment. Our catalog includes both smooth and barbed connection options in various insertion lengths, allowing customers to select the probe that matches their duct dimensions and tubing type. We provide detailed specifications for each product, including dimensions and connection sizes, to assist with selection. For technical support or to request a quote, contact our team. We can help identify the appropriate probe for your application and provide lead time and pricing information. Our goal is to make it straightforward for maintenance and procurement teams to source the Cleveland Controls components they need.

Frequently asked questions

Common questions about CLEVELAND CONTROLS from 3G Electric.

What is the difference between a smooth and barbed process connection on Cleveland Controls static pressure probes?

Smooth process connections have a straight, untextured outer surface designed for push-on tubing, typically secured with a clamp or compression fitting. Barbed process connections feature a raised ridge or barb that grips flexible tubing from the inside, and they include a metal barbed hose adapter. The choice depends on the tubing type and the desired connection method. Smooth connections are often used with rigid or semi-rigid tubing, while barbed connections are common with flexible rubber or plastic tubing. Both types are available in various sizes, such as 1/2 in or 1 in, to match common tubing diameters.

How do I select the correct insertion length for a Cleveland Controls static pressure probe?

Insertion length is the portion of the probe that extends into the duct or plenum. It should be long enough to reach the airstream but not so long that it obstructs airflow or interferes with internal components. For small ducts, a shorter insertion length such as 1 1/2 in or 2 in may be sufficient. For larger ducts or where the probe must pass through insulation, longer lengths like 6 in or 8 in are available. Consider the duct dimensions and the location of the measurement point. The probe should be installed perpendicular to the airflow, with the tip facing upstream. Ensure the insertion length does not exceed the duct width to avoid contact with the opposite wall.

What materials are Cleveland Controls static pressure probes made from?

Cleveland Controls static pressure probes are typically constructed with a metal body, such as aluminum or stainless steel, depending on the model. The specific material is not always listed in the product specifications, but the probes are designed for durability in HVAC and industrial environments. The barbed hose adapters included with some models are also metal. For applications with corrosive gases or high humidity, verify material compatibility with the manufacturer or consult the product datasheet. In general, these probes are suitable for air and non-corrosive gas pressure measurement.

Can Cleveland Controls static pressure probes be used with differential pressure switches?

Yes, static pressure probes are commonly used with differential pressure switches to sense pressure in ducts and plenums. The probe provides a pressure signal via tubing to the switch, which then actuates an electrical contact based on the pressure difference. Cleveland Controls manufactures both the probes and a range of pressure switches, so they can be paired for a complete sensing solution. When selecting a switch, consider the pressure range, setpoint, and electrical ratings. The probe's connection type and size must match the tubing used to connect to the switch. For high-pressure applications, ensure the probe and switch are rated for the maximum pressure.

What is the purpose of the metal barbed hose adapter included with some Cleveland Controls static pressure probes?

The metal barbed hose adapter is provided with barbed process connection probes to facilitate a secure connection to flexible tubing. The adapter slides into the tubing, and the barb helps retain the tubing without additional clamps, although clamps may still be used for extra security. This adapter is particularly useful when the probe's process connection is barbed, as it provides a smooth transition to the tubing. It is made of metal for durability. The adapter is included with models that have a barbed connection, such as those with 1/2 in or 1 in barb sizes. It is not used with smooth connection probes.
