| Content | The Amprobe TMA-21HW Hotwire anemometer technology eliminates the use of bearings and rotating parts. When compared to standard bearing type probes, the compact Amprobe hotwire sensor is more reliable (no mechanical moving parts) and allows for easier access to duct and confined spaces. The Amprobe TMA-21HW Hotwire anemometer measures air flow volume and velocity, it features a telescopic probe for positioning the sensor, and is used by HVAC/R technicians to measure wind flow and temperature in air conditioning systems. | The Amprobe SC-3500 4? Signal Clamp for AT-3500 attaches around a buried metallic pipe, cable, or wire to induce a transmitted signal into the feature for active location and tracing. It does not require direct contact with metal to transmit the signal and can transmit signal through insulation on wires and into cable and wire bundles, providing more accurate tracing than locating with just a receiver and transmitter. Accommodates conductors up to 4? in diameter. Transmits a 33 kilohertz (kHz) frequency supplied by the T-3500 Transmitter (included in the AT-3500 kit). | Universal, economical tachometer measuring rotational or surface speed either in contact or non-contact way. Widely used to measure rotational speed of motors, conveyer belts and other moving or rotating systems. | | If you install or connect 3-phase motors and systems, you recognize the importance of verifying the correct motor rotation and wiring phase sequence. Improper connections can cause motors to rotate in reverse direction, potentially damaging the motor and the equipment it is powering. | The Amprobe MLS55-3 Pipe transmitter is an optional accessory for the AT-3500 underground cable locator that allows for pinpointing places in pipes, ducts, etc. It can be inserted to the pipe/duct using standard fish tape or a duct rodder and can accommodate pipes over 2? (5 cm) in diameter. |
