The 100/200 systems are designed around small yet rugged transmitter modules capable of operating in hostile industrial environments with temperatures to 175° and static acceleration to 50,000 G. The modules are not affected by contaminants such as oil, dirt, water or other industrial impurities and are powered by induction. An induction power system operates similar to an air gap transformer where the primary winding is stationary, and the secondary winding rotates. Secondary "rotation" can be from 0 RPM to very high RPM's. Successful operation to 75,000 RPM and above has been achieved. Optional battery power operation is available where induced power is not practical.

In operation, physical phenomena (stress, temperature, etc.) are sensed by a transducer (strain gauge, thermocouple, etc.) and converted to a frequency modulated electronic signal by the transmitter module. The modules are located on the assembly with the sensor(s) and transmit the electronic signals across the rotating/stationary interface to an adjacent stationary antenna. The signal is conditioned in a receiver and data can be displayed directly in engineering units. Analog outputs are available for use with recorders and displays.

SPECIFICATIONS
The 100/200 Series consists of a series of transmitters and a receiver module which includes a 155W receiver and signal conditioning cards corresponding to the transmitter.

The E series is rectangular. This series requires an additional U-core or transformer for coupling induction power to the transmitter. An antenna pin is available to connect the RF signal to the transmitting antenna.
　

The H series is rectangular with a built-in RF coupling plate and induction power pickup coil.
　

The R series is cylindrical in shape and has a transformer coupled power input and an antenna pin for coupling the RF signal to the antenna.

Piezoelectric Interface Module:

Receivers:

The receiver for a 100/200 system is a Model 155W which consists of a 155W receiver module and a signal conditioning card.

The standard 155W Receiver module is capable of tuning to signals anywhere in the FM radio band of 88 to 108 MHz. The 155 Receiver module is also available with frequency ranges of 75 to 89 MHz, 64 to 76 MHz, and 54 to 65 MHz as an option. Signal conditioning cards of various types plug into the receiver module. The type of signal conditioning card used depends on the type of transmitter. Together, the receiver module and signal conditioning card form a modular unit. The receiver modules are approximately 3" x 5" x 11" and are designed to fit a 155W receiver mainframe rack. The mainframe rack is 18" x 5.5" x 14" and up to five receiver modules can be plugged into a single frame, along with a power supply. One power supply provides power to all modules.

Receiver - 155W:
	FULL SCALE DATA OUTPUT	1V to 5V based on signal conditioning card
	OPERATING TEMP. RANG	-15°C to +65°C
	COMPENSATED TEMP. RANGE	0°C to +50°C

	INPUT POWER--AC	90 to 130 VAC, 50 to 63 Hz
	WEIGHT	1.1 kilograms (2.5 pounds)

	OPTIONS:
	INPUT POWER - AC	180 to 250 VAC
	RECEPTION FREQUENCIES	54 to 87 MHz

Power Supply:
The 100/200 series will have two power supplies, one for the transmitter and one for the receiver. The transmitter power supply will be induction or battery.
Induction:	Model 160 Induction Oscillator and Model 160 PS DC Power Supply. The 160 PS output voltage is adjustable from zero to 30V. Current output capability is 3A. NOTE -- When transmitters built specifically for battery operation (such as the 204, 205, and 208 are used in an induced power configuration, a 230C Regulator is used to provide regulated voltages of approximately 2.5 VDC. The regulator is excited by a 160 kHz source via rotary coil. The regulator can simultaneously provide isolated power to two transmitters.
Battery:	Lithium batteries are provided in various configurations, which provide long life while maintaining complete safety. The lithium battery has several cells connected in series-parallel, with an output greater than 3V. A precision Schottky diode is added to reduce the output to 2.7V in some batteries.
Model 435A VHF Amplifier is used in systems where long cable runs (more than 75 meters) are necessary between the RF pickup point at the stationary antenna and receiver. It is also required where there are large RF losses due to distribution when multiple receivers are used. The receiver power supply will normally be a 155W AC or 155W DC which are plug-ins for the receiver mainframe rack (see discussion under receivers above).

Module Support Ring:

Because of the numerous and unique applications of the 100/200 series, there is not a standard module support ring (collar). The most commonly used collar is the clamp-on collar. However, in low-speed applications simple tape arrangement or strap-on collars can be used. In extremely harsh environments custom designs will be required. We are prepared to design, fabricate and/or install these unique module support rings.

Antenna:

Antennas, like power supplies, must be split between the rotating antenna (transmitter side) and the stationary antenna (receiver side).

The antennas on the transmitter side are further split into: a) battery powered and R Series, and b) H and E Series. The battery powered and R Series transmitter's antenna can be a small (less than 1 square inch) plate or if that is not practical, a short (less than 4 inches) wire can be used. The H and E Series transmitters have the antenna plate built in.

The antennas for the receiver side can be as simple as a conductive metal loop (often from 5/32 inch diameter brass) but can be very complex in unique environments. The simple loop arrangement works well for loop diameters of 8 inches or less. Over 8 inches special steps must be taken. Technical notes are available and we have many years of experience in solving antenna problems.
