Microwave TV Transmitters for Radio Amateurs
-
Is the transmission of broadcast quality video and audio over the wide range of frequencies of radio waves allocated for radio amateur (Ham) use.[1] ATV is used for non-commercial experimentation, pleasure and public service events. Ham TV stations were on the air in many cities before commercial television stations came on the air.[2] Various transmission standards are used, these include the broadcast transmission standards of NTSC in North America and Japan, and PAL or SECAM elsewhere, utilizing the full refresh rates of those standards. ATV includes the study of building of such transmitters and receivers, and the study of radio propagation of signals travelling between transmitting and receiving stations.[

Force Transmitter
LKVE/i
-
The PIAB LKVE electronic overload protection system consists of a force transmitter with amplifier and an electronic signal processing unit. The PIAB LKVE force transmitter is attached to a stationary line part. The rope is deflected via a slight angle between the two wheels and the clamping jaw. When loaded, the rope tends to straighten and applies a force which is transmitted to the load cell. The load cell in the PIAB LKVE delivers a signal proportional to the force on the load cell. The signal is amplified and is converted to 4-20mA. This standardized signal (4-20mA) allows distances between the force transmitter and the electronic unit to be 500 m.

Gauges and Transmitters
-
Meriam offers a wide variety of mechanical and digital pressure gauges for process measurement and indication. Terrific accuracy specifications and little-to-no temperature effect set these instruments apart from the competition. Many of our digital gauge products have multiple output options to increase their versatility in today's changing control schemes. Mechanical gauges have been the reliable standard in pressure measurement and still have their place in today's industrial environment. They excel in areas where digital units cannot function, such as in very cold installations.
