MAMAC

MAMAC Systems is a manufacturer of sensors, transducers, and controls for HVACR and building automation applications. The company, founded in the United States, produces a range of measurement and control devices used in commercial and industrial environments. 3G Electric supplies MAMAC replacement HVACR controls, switches, thermostats, and related components to a global customer base. The product line includes duct temperature sensors, humidity sensors, electronic pressure transducers, power supplies, and combination temperature and humidity sensors. These devices are typically used in air handling units, ductwork, and environmental monitoring systems where accurate measurement of temperature, humidity, and pressure is required. MAMAC sensors are available with various output signals, including voltage (VDC) and current (mA), allowing integration with building management systems (BMS) and programmable logic controllers (PLCs). The sensors are designed for installation in HVAC ducts, with probe lengths and mounting configurations suited for standard duct sizes. The electronic pressure transducers, such as the A-520 series, are used for measuring differential or static pressure in air or non-corrosive gas applications. Power supplies like the PS-200 series provide regulated DC power for MAMAC transmitters and sensors. 3G Electric stocks multiple SKUs of MAMAC products, supporting maintenance and replacement needs for existing installations. The availability of these components enables plant engineers and maintenance managers to source direct replacements for failed or aging sensors without system redesign. MAMAC products are typically specified for their compatibility with standard HVAC control systems and their ability to operate in the temperature and humidity ranges common in commercial buildings. The sensors are built with materials suitable for indoor air handling environments, and their specifications include accuracy and response times appropriate for control applications. 3G Electric provides logistics support for global shipment, ensuring that MAMAC components reach facilities worldwide. For procurement specialists, the range of MAMAC sensors and transducers offers a straightforward path to maintaining system performance through direct replacement of OEM or third-party components.

Frequently asked questions

Common questions about MAMAC from 3G Electric.

What types of MAMAC sensors are available from 3G Electric?

3G Electric stocks MAMAC duct temperature sensors (e.g., TE-702-B-7-B, TE-703-D-17-A-1), humidity sensors (e.g., HU-921-VDC-7, HU-921-MA-8, HU-225-2-MA), and combination temperature and humidity sensors (e.g., HU-225-2-MA). These sensors are designed for HVACR applications and are available with various output signals such as 0-10 VDC or 4-20 mA.

Are MAMAC electronic pressure transducers compatible with standard HVAC control systems?

Yes, MAMAC electronic pressure transducers, such as the A-520-2-A-1, are designed for use in HVAC systems to measure differential or static pressure. They typically output a 0-5 VDC or 4-20 mA signal, which can be directly interfaced with building management systems (BMS) or PLCs. The transducers are suitable for air or non-corrosive gas applications.

What power supply options does MAMAC offer for their sensors?

MAMAC power supplies, such as the PS-200-1-B-1-L, provide regulated DC power for their transmitters and sensors. These power supplies are typically used to convert line voltage (e.g., 120 VAC or 230 VAC) to a stable DC output (e.g., 24 VDC) required by MAMAC devices. They are designed for panel or enclosure mounting.

Can MAMAC humidity sensors be used in outdoor or high-moisture environments?

MAMAC humidity sensors, such as the HU-921 series, are primarily designed for indoor duct mounting in HVAC systems. They are not typically rated for outdoor or condensing environments unless specified. For high-moisture areas, consult the sensor's IP rating and operating humidity range. Most MAMAC humidity sensors are intended for dry, non-condensing conditions.

How do I select the correct MAMAC temperature sensor for my duct application?

Selection depends on the required temperature range, probe length, and output signal. MAMAC duct temperature sensors like the TE-702-B-7-B and TE-703-D-17-A-1 are available with different probe lengths and thermistor or RTD elements. Verify the sensor's temperature range (e.g., -40 to 150°F) and output type (e.g., 10k ohm thermistor or 4-20 mA) to match your control system.

Does 3G Electric carry MAMAC replacement parts for existing HVACR installations?

Yes, 3G Electric stocks MAMAC replacement HVACR controls, switches, and thermostats, including sensors, transducers, and power supplies. These are direct replacements for MAMAC components in existing systems. The inventory includes multiple SKUs to cover common models, and logistics support is available for global shipping.
