TEMPO

TEMPO is a brand historically associated with telecommunications test equipment and, more recently, with underground utility locating and marking products. The product families supplied by 3G Electric under the TEMPO name include underground utility locators, utility marker spikes, and related accessories. These products are used to identify, trace, and mark buried infrastructure such as gas lines, water mains, electrical cables, and telecommunications conduits. The TEMPO 521E valve and wire locator operates at 1750 Hz in active mode with a transmitter, provides digital, audible, and light indication, and has a maximum locating depth of 8 ft. It supports direct connection for tracing conductive utilities. The marker spike range includes passive markers that transmit specific frequencies for detection with compatible locators. For example, the SM11 transmits 66.4 kHz, the SM12 transmits 77 kHz, the SM16 transmits 121.6 kHz, the SM18 transmits 145.7 kHz, and the SM19 transmits 169.8 kHz. These spikes are constructed with polyethylene housings and are available in color-coded options: purple, black/orange, green, blue, and red. The SMFIX is a black utility spike holder for securing markers, and the SMAD1 is a black marker spike for general marking. The color coding aligns with common industry practices for identifying utility types, though specific assignments should be verified against project specifications. The polyethylene housing material provides durability for insertion into soil and resistance to environmental exposure. These products are intended for use during construction, excavation, and maintenance activities to reduce the risk of accidental damage to buried lines. 3G Electric supplies the TEMPO line as part of its broader portfolio of industrial equipment, including burners, pumps, and gas controls. For technical buyers, 3G Electric provides access to product specifications, manufacturer part numbers, and support for selecting the appropriate locator or marker based on frequency, depth requirements, and site conditions. The company serves plant engineers, maintenance managers, and procurement specialists globally, with the ability to ship to international locations. The TEMPO products listed are identified by manufacturer part numbers such as 521E, SMFIX, SM11, SM12, SM16, SM18, SM19, and SMAD1, which can be used for cross-referencing and procurement. When specifying TEMPO locators and markers, consider the operating frequency compatibility between the locator and marker spikes, the required locating depth, and the environmental conditions of the installation. The 521E locator's 1750 Hz active mode is suited for tracing conductive lines when a transmitter is connected, while the passive markers are detected by locators tuned to their respective frequencies. The marker spikes are designed for direct burial or surface placement to provide a detectable and visible indication of underground assets. 3G Electric can assist with identifying the correct part numbers and quantities for specific project needs, ensuring that the selected TEMPO products match the application requirements. For procurement, the manufacturer part numbers and SKU numbers are provided to facilitate accurate ordering. The TEMPO line complements other industrial equipment offered by 3G Electric, allowing for consolidated sourcing of utility locating and marking supplies alongside other plant equipment.

Frequently asked questions

Common questions about TEMPO from 3G Electric.

What is the maximum locating depth of the TEMPO 521E locator?

The TEMPO 521E valve and wire locator has a maximum locating depth of 8 ft. It operates at 1750 Hz in active mode with a transmitter and provides digital, audible, and light indication. This depth is suitable for typical buried utility tracing where the line is within 8 ft of the surface. For deeper utilities, alternative methods or equipment may be required. The 521E supports direct connection for conductive tracing, which can improve signal strength on metallic pipes and cables. When using the 521E, ensure the transmitter is properly grounded and connected to the target line for active locating.

What frequencies do TEMPO utility marker spikes transmit?

TEMPO utility marker spikes transmit specific frequencies for passive detection with compatible locators. The SM11 transmits 66.4 kHz, the SM12 transmits 77 kHz, the SM16 transmits 121.6 kHz, the SM18 transmits 145.7 kHz, and the SM19 transmits 169.8 kHz. These frequencies are used by locators tuned to the same frequency to detect the marker. The spikes are color-coded: purple (SM11), black/orange (SM12), green (SM16), blue (SM18), and red (SM19). The SMAD1 is a black marker spike without a specified transmission frequency. Always verify that your locator supports the frequency of the marker spike being used.

What material are TEMPO marker spikes made of?

TEMPO marker spikes such as the SM11, SM12, SM16, SM18, and SM19 are made with polyethylene housings. Polyethylene is a durable thermoplastic that resists moisture, chemicals, and impact, making it suitable for burial in soil. The spike shape allows for insertion into the ground. The SMFIX is a black utility spike holder, also intended for securing markers. The SMAD1 is a black marker spike, but its housing material is not specified in the available data. For applications requiring chemical resistance or extended UV exposure, confirm the specific material properties with the manufacturer's datasheet.

How do I choose between TEMPO marker spikes and the 521E locator?

TEMPO marker spikes and the 521E locator serve different functions. Marker spikes are passive devices buried or placed at utility locations to provide a detectable signal at a specific frequency when scanned by a compatible locator. The 521E is an active locator that can trace conductive lines when connected to a transmitter, operating at 1750 Hz. Use marker spikes for long-term marking of non-conductive or conductive utilities where a passive marker is preferred. Use the 521E for active tracing of conductive pipes and cables. In some workflows, both are used: markers for identification and the locator for tracing. Select based on whether you need to detect a pre-installed marker or actively trace a line.

What is the TEMPO SMFIX used for?

The TEMPO SMFIX is a black utility spike holder. It is designed for marking and securing underground utility lines. The holder provides a means to mount or retain a marker spike, likely for placement in the ground or on a surface. It is identified by manufacturer part number SMFIX. The SMFIX does not transmit a frequency; it is an accessory for holding or securing marker spikes. For specific installation instructions and compatibility with TEMPO marker spikes, refer to the manufacturer's documentation. 3G Electric can provide the SMFIX as a standalone item or as part of a system with compatible TEMPO markers.

Can TEMPO marker spikes be used for gas, water, and electric lines?

TEMPO marker spikes are used for marking underground utilities, including gas, water, electric, and telecom lines. The color coding of the spikes—purple, black/orange, green, blue, and red—is commonly associated with different utility types, but the specific color-to-utility assignment can vary by region or project specification. The spikes transmit frequencies that are detected by compatible locators, allowing identification without excavation. For gas lines, for example, a specific color and frequency may be used according to local guidelines. Always verify the required color and frequency for your application against applicable standards. The polyethylene housing is suitable for direct burial in soil.
