The Loop-Mates are single function low-cost pocket sized units, designed for test and calibration of process loops.
Simplicity of operation is their key – no keypads or complicated selections. Engineers will be able to pick them up and get to work immediately. Just select 4 – 20mA, or 10V loop, and TxSim, RxTest, RxSim or TxTest. Both have internal loop drive supplies, which can be used to power the loop if required.
Loop-Mate 1 is the simulator and acts as a source to provide the loop signals, 4 – 20mA or 0 – 10V. No complicated selection of the output, just operate up/down buttons to increase or decrease the signal. There are 7 set-points, 0%, 10%, 25%, 50%, 75%, 90%, 100%. Each is indicated on a high brightness LED and an audible beep sounds as you step between them. Auto-stepping mode (adjustable rate) allows Loop-Mate1 to be left connected stepping up and down. The engineer can then move to another location to check (using Loop-Mate 2) that the signal is arriving correctly and is within specification.
Loop-Mate 2 is a dedicated loop signal indicator, just as easy to operate. Once again select the loop type, 4 – 20mA, or 0 – 10V, and whether you want the display in direct units, or % of span. The LCD display shows the signal to an accuracy of 0.05% either in mA, V, or % of span.
Both units are powered by a single standard PP3 battery that gives up to 40 hours continuous use.
L’enregistreur portable DAS220 a été conçu pour répondre à toutes les applications process : mesures de tension, mesure sur les capteurs (0-10v), mesures de température (thermocouple, Pt100-Pt1000), mesures de courant (avec adaptateur en option), mesures de résistance, comptage, fréquence. Vous pouvez visualiser vos mesures (courbes, valeurs numériques) et réaliser vos acquisitions directement dans la mémoire interne de l’appareil ou sur clé USB. Le transfert et l’exploitation des données se fait ensuite sur PC à l’aide du logiciel DasLab fourni.
Les enregistreurs Sefram DAS30/50/60 ont été conçus pour répondre efficacement à toutes les mesures réalisées dans le milieu industriel (CEI 1010, CAT. III 600V).
The 7000 is a portable process control instrument that combines a precision digital thermometer (using RTD probes) with an RTD/ohms calibrator.
The 1090 is a high performance portable process calibrator that combines source and measurement functions for thermocouples, PT100s, µV, mV, and mA. As a multifunction instrument the 1090 combines accuracy and durability with simple operation, making it ideal for process plant applications.
The 1049 is a handheld precision simulator for PT100 0.3850 platinum resistance elements used for accurate temperature measurement.
