The Telco remote transmitter (LT) and receiver (LR) sensors, in combination with a Telco photo amplifier (PA), will operate problem-free through steam, oil, grease, water, fog, dirt and most other contaminations that would cause other infrared sensors to fail. This new high-performance photo amplifier is based on the latest microprocessor technology with full gain control, on-off time delay, signal level indication with a supply voltage ranging from 24 V a.c./d.c. to 115 and 230 V a.c. The microprocessor controlled photo amplifier continuously surveys both the remote transmitter and receiver. If the cable to the sensor breaks, or if the sensor has an internal electrical failure, two individual LEDs on the front of the photo amplifier - one for the transmitter and one for the receiver - will clearly indicate the failing one, for easy replacement.
Telco remote sensors have a very small physical size - available either in stainless steel or polycarbonate - which ensures easy installation. They are also both shock and vibration proof due to their fully encapsulated epoxy sealed construction as well as being insensitive to a high degree of direct sunlight and are very easy to align, even at long distances of over 70 m.
Telco, represented locally by Gail Norton Instrumentation, has been manufacturing high-performance infrared sensors for demanding industrial applications since 1975.
