TR91-176 Temperature Sensors

PM and SM Versions; Panda PM or SM Fiber; 780 to 1550 nm; 3 Ports; Insertion Loss ≤0.7 to ≤1.0 dB Fiber optic circulators act as signal routers, transmitting light from an input fiber to an output fiber, but directing light that returns along that output fiber to a third port. They perform a similar function as an isolator, protecting the input fiber from return power, but also allowing the rejected light to be employed. OZ Optics miniature inline circulators are ideal for OEM applications. They are available with either singlemode or polarization maintaining fiber. OZ Optics’ PM fiber optic circulators are manufactured with polarization maintaining fibers, making them ideal for polarization maintaining applications such as 40 Gbit systems or Raman pump applications. They are also used in double pass amplifiers and in chromatic dispersion compensation modules.  The standard PM fiber alignment is for all power to be transmitted along the slow axis of each fiber (Fast axis blocking). With OZ Optics’ modular design and custom manufacturing capabilities, any of the three ports can be aligned for fast axis coupling. High extinction ratio connectors can also be installed. Regardless of the state of polarization of the return beam, the input fiber will still be isolated from reflected light. For non-telecom wavelengths and high power applications, the cube style circulator is offered. This design is well suited for custom applications. Additional connector and cable options and custom designs are also available. Please forward a detailed description of your application to us.

NTC Thermistor;±1,0°C;10 kΩ @25°C;Cylindrical

25 A; Single Channel; Input 12-36 VDC, Output 0-36 VDC; RS232; Board LevelThe Bi-directional or unidirectional H-bridge configuration of the 5R7-001 temperature controller creates a seamless transition between heating and cooling as it commands the thermoelectric modules. The included user friendly PC software makes it easy for the user to change control configurations through the RS232 interface which has 1500VAC isolation from the electronic circuitry, virtually eliminating interference from noise or errant signals. Once the 5R7-001 temperature controller is set-up, the computer may be disconnected and the 5R7-001 temperature controller becomes a stand alone unit or the computer can remain connected for data acquisition. The temperature may also be set through the optional display for the 5R7-001 or remote potentiometer. The load circuit is pulse width modulated at 2.7 Khz and delivers a load current of .1 to 25 Amps. Model 5R7-001 specifications: Input Voltage: 12 to 36 VDC Output Voltage: 0 to 36 VDC Load Current: 0.1 to 25 A Temperature Resolution: 0.01°C PID Functions: Bandwidth: 0.1 to 50°C Integral: 0 to 10 repeats per minute Derivative: 0 to 10 minutes PWM Base Frequency: 2.7 Khz Ambient Temperature range: -20 to 70°C Power Dissipation: < 10 Watts Process Control Rate: 90 time per second Output Power Resolution: ± 0.2% Control Resolution: ± 0.01°C Dimensions: 2” H (2.64” with HS) x 6” W x 3.63” D Model 5R7-001 features: H-Bridge Control PC Programmable PID or On/Off Control PC Configurable Alarm Circuit 0-36 VDC Output using Split Power Supply RS232 Communication Port RoHS Compliant Set Temperature range of –40 to 250°C Large program memory space for customization
