Johnson Controls T-5210-1118 Transmitter

The Johnson Controls T-5210-1118 Transmitter is a high-precision pneumatic temperature transmitter engineered for professional HVACR control systems. Designed for accurate temperature sensing across a 0 to 100°F operating range, this direct-acting pneumatic transmitter converts thermal data into a proportional 3 to 15 psig output signal. It features a 17-foot copper averaging element paired with a 1-foot copper capillary, making it the ideal solution for monitoring duct air temperatures where stratification is a concern. The integration of pneumatic feedback ensures an exact relationship between measured variables and the transmitted signal, maintaining system linearity and stability. This rugged unit operates on a 20 psig supply pressure and consumes approximately 45 SCIM, featuring a ball-type control port and bimetal element to compensate for ambient temperature fluctuations. Whether you are performing a HVAC pneumatic control system retrofit or a new installation, the T-5210-1118 provides the reliability required for sensitive environmental controls.

Key Benefits

• Broad Average Sensing: The 17-foot copper averaging element eliminates errors caused by air stratification in large ducts.
• Precision Linearity: Features a reinforced lever and bimetal compensation to ensure accurate signal transmission despite ambient changes.
• Simplified Diagnostics: Equipped with an integral hypodermic needle test point for rapid field pressure verification.
• Versatile Mounting: Designed to operate in any position on a rigid flat surface, compatible with standard duct flanges and wells.

Common Questions

Does this unit require a restricted air supply?
Yes, for proper operation, the Johnson Controls T-5210-1118 requires a 0.007-inch restricted air supply to maintain signal integrity.

Can I use this for dew point sensing?
When paired with a locally purchased Dewcel, this transmitter can be adapted to function as a dew point transmitter.

Are field repairs recommended for the internal components?
Factory calibration is fixed on these units; field repairs to the internal mechanism are not recommended. However, the outer cover is replaceable using part T-5210-602.
