Description The sensors of the optris CS series are non-contact infrared temperature sensors. They calculate the surface temperature based on the emitted infrared energy of objects [► Basics of Infrared Thermometry]. The sensor housing of the optris CS is made of stainless steel (IP63) and contains the complete sensor electronics. The optris CS has a fixed mounted connection cable. The sensors CS are sensitive optical systems. Please use only the thread for mechanical installation.
Cautions Avoid abrupt changes of the ambient temperature. In case of problems or questions which may arise when you use the CS, please contact our service department. Read the manual carefully before the initial start-up. The producer reserves the right to change the herein described specifications in case of technical advance of the product.

Optical Charts The following optical charts show the diameter of the measuring spot in dependence on the distance between measuring object and sensing head. The spot size refers to 90 % of the radiation energy. The distance is always measured from the front edge of the sensor housing/ CF-lens holder/ air purge. The size of the measuring object and the optical resolution of the infrared thermometer determine the maximum distance between sensing head and measuring object.
Close Focus Optics The optional CF-lens allows the measurement of small objects. The CF optics can also be combined with a laminar air purge: CF-lens [ACCTCF] Laminar air purge with integrated CF-lens [ACCTAPLCF] If the CF-lens is used, the transmission has to be set to 0,78. To change this value the optional USB-Kit (including CompactConnect software) is necessary.
LED Functions The green LED can be programmed for the following functions. For the programming the USB adapter cable incl. software (option) is necessary. The factory default setting for the LED is self diagnostic.
Self Diagnostic With this function the current status of the sensor will be indicated by different flash modes of the LED.
Temperature Code Indication With this function the current measured object temperature will be indicated as percentage value by long and short flashing of the LED. At a range setting of 0-100 °C 0-100% the LED flashing indicates the temperature in °C.
Installation Mechanical Installation The CS is equipped with a metric M12x1 thread and can be installed either directly via the sensor thread or with the help of the both hex nuts (standard) to the mounting bracket available. For an exact aiming of the sensor to an object the LED function ► Automatic Aiming Support can be used.
Mounting Accessories Mounting bracket, adjustable in one axis [ACCTFB] Mounting bolt with M12x1 thread, adjustable in one axis [ACCTMB] Mounting fork with M12x1 thread, adjustable in 2 axes [ACCTMG] The Mounting fork can be combined with the Mounting bracket [ACCTFB] using the M12x1 thread.
Air Purge Collars The lens must be kept clean at all times from dust, smoke, fumes and other contaminants in order to avoid reading errors. These effects can be reduced by using an air purge collar. Make sure to use oil-free, technically clean air, only.
Further Accessories Right angle mirror Enables measurement with 90° angle [ACCTRAM] Protective window same mechanical size as CF lens [ACCTPW] USB-Kit: USB adapter cable incl. terminal block and software CD [ACCSUSBK] If the protective window is used, the transmission has to be set to 0,83. To change this value the optional USB-Kit (including CompactConnect software) is necessary. ► All accessories can be ordered using the according part numbers in brackets [ ].
Electrical Installation Please use a stabilized power supply unit with an output voltage in the range of 5–30 VDC which can supply 100 mA. The residual ripple should be max. 200 mV. Analog device (mV output on OUT pin) The output impedance must be ≥ 10kΩ. Analog device (thermocouple type K output on OUT t/c K pins / only at model CSTCLT15) The output impedance must be ≥ 20 Ω.
On the model CSTCLT15 you can choose between a mV output (0-5 or 0-10 V; scalable via software) and a thermocouple output type K. The factory default setting is thermocouple output. ► Factory default settings This output supplies a voltage according to the t/c characteristic curve type K. If you want to extend this output you have to use a suitable thermocouple extension cable (NiCr-Ni). IMPORTANT: The shield [black] on the CS is not connected to GND [brown].
The sensor is offering two ways of digital communication: bidirectional communication (sending and receiving data) unidirectional communication (burst mode – the sensor is sending data only) Open collector output The open collector output is an additional alarm output on the CS and can control an external relay e.g. In addition the analog output can be used simultaneously.
Direct connection to an RS232 interface on the computer For a bidirectional RS232 connection of the sensor the following interface circuit can be used: MAX3381E (manufacturer: Maxim): Model UART voltage (RxD) UART voltage (TxD) CSv1/ CSMv1 5V 5V CSv2 3,3 V 2,5 V CSMv2 3,3 V 2,5 V previous sensor versions: CSv1 CS/ version 1 (→ 12/2010) CSMv1 CSmicro/ version 1 (→ 09/2011) optris CS – E2012-10-B 22 CSM2W/ CX 3,3 V 2,5 V

Software CompactConnect Installation Insert the installation CD into the according drive on your computer. If the autorun option is activated the installation wizard will start automatically. Otherwise please start setup.exe from the CD-ROM. Follow the instructions of the wizard until the installation is finished.
Communication Settings Serial Interface Baud rate: Data bits: Parity: Stop bits: Flow control: 9600 baud 8 none 1 off Protocol All sensors of the CS series are using a binary protocol. To get a fast communication the protocol has no additional overhead with CR, LR or ACK bytes. To power the sensor the control signal „DTR“ has to be set.

Basics of Infrared Thermometry Depending on the temperature each object emits a certain amount of infrared radiation. A change in the temperature of the object is accompanied by a change in the intensity of the radiation. For the measurement of “thermal radiation” infrared thermometry uses a wave-length ranging between 1 µ and 20 µm. The intensity of the emitted radiation depends on the material.
Emissivity Definition The intensity of infrared radiation, which is emitted by each body, depends on the temperature as well as on the radiation features of the surface material of the measuring object. The emissivity (ε – Epsilon) is used as a material constant factor to describe the ability of the body to emit infrared energy. It can range between 0 and 100 %. A “blackbody” is the ideal radiation source with an emissivity of 1,0 whereas a mirror shows an emissivity of 0,1.
► Cove a part of the surface of the measuring object with a black, flat paint with an emissivity of 0,98. Adjust the emissivity of your infrared thermometer to 0,98 and take the temperature of the colored surface. Afterwards, determine the temperature of a directly adjacent area and modify the emissivity until the measured value corresponds to the temperature of the colored surface. CAUTION: On all three methods the object temperature must be different from ambient temperature.

Appendix C – Smart Averaging The average function is generally used to smoothen the output signal. With the adjustable parameter time this function can be optimal adjusted to the respective application. One disadvantage of the average function is that fast temperature peaks which are caused by dynamic events are subjected to the same averaging time. Therefore those peaks can only be seen with a delay on the signal output.
