Temperature indicator PMT-920

digitalpanel-mountprogrammable

Programmable indicator PMT-920 is applicable to cooperation with the temperature sensors. Indicator works with resistance sensor Pt (Pt100, Pt500, Pt1000). PMT-920 can be connected with 2-, 3- or 4- wire sensors. Indicator recognize 3- and 4- wire sensors and compensate line resistance automatically. Two alarm values controlling the relay outputs can be programmed. Diodes on the front of the indicator indicate the exceeding of the alarm values. The relay outputs have a pair of operating contacts. PMT-920 meters enables the following parameters to be programmed: ¨ level and hysteresis of action of relays; ¨ state of contact during alarm; ¨ password restricting access to the programming menu; ¨ display filtering level. ¨ color of display (green or red).
