There are the following options of alarm indication:
ALARM INDICATION OPTIONS | |
---|---|
E-mail: | In case of alarm creation warning e-mail message is sent to addresses defined by the user (maximum three addresses) or via e-mail to SMS message. |
SNMP: | In case of exceeding of adjusted temperature limits alarm is activated and warning trap is sent to user specified IP addresses (maximum 3 addresses). |
WWW pages: | In case of exceeding of adjusted temperature limits active alarm is displayed on www page. |
syslog: | Online thermometer enables to send text messages to selected syslog server after different events appear. |

Four-channel thermometer P8541 |
Included accessory:
Traceable calibration certificate from the manufacturer, instruction manual.
Calibration certificate with declared metrological traceability of etalons is based on requirements of EN ISO/IEC 17025 standard.
Example of calibration certificate.
TSensor - freeware for online configuring of the transmitter is ready to download.
SensorReader - freeware for online logging values from one transmitter to a PC disk file is ready to download. Program enables to alarm acoustically the PC user if adjusted alarm limits are exceeded. Recorded values in CSV format are easy to process in e.g. Excel. Program can be started several times on a computer at the same time to monitor values from several transmitters.
For acquiring values from several transmitters, also third party software is possible to use. Tested functionality is with programs:
LabVIEW from National Instruments, by means of the free Modbus Library for LabVIEW.
For viewing of actual values and graphs following examples of application were created in LabVIEW 8.5 :
P851x-Ethernet.vi for single channel thermometers P8510, P8511
P8541-Ethernet.vi for quad channel thermometers P8541
TIRS.NET - transmitters are also directly supported by program TIRS.NET from Coral s.r.o. company. Please download demo enabling full work with transmitters.
Tested functionality is also with programs:
Advanced Host Monitor,
ControlWeb,
EasyView.
For record of values to graphs via web interface, project Cacti
www.cacti.net
is available.
