Features • Whole stainless steel housing, IP67 protection • OLED, pressure and switch state display • Compact, body rotate 320° • Protections for over-voltage, over-current and reversed polarity • Anti-electromagnetic design under complex electromagnetic environment • Analog output (4mA~20mA DC)+2-way PNP, 2-way PNP, 2-way NPN, 1 relay output for options • Restore factory settings, linear correction • Support unit switch-over between °C and F Introduction MTM5881 is an intelligent temperature switch combining temperature measurement, display and control together. The sensor output signal is amplified, noise reduced and conditioning through a highly integrated microprocessor to realize accurate temperature measurement, display and control of the switching output. The product adopts whole stainless steel housing, the protection is IP67. The indicator can be freely rotated within 320°. The product’s amplifier circuit has over-voltage, over current and reversed polarity protection. It can be used in complex electromagnetic environment of industrial sites. It has diversified output options including analog output (4mA ~ 20mA DC) +2 way PNP, 2-way PNP, 2-way or one-way relay. Also it supports manually cleared and switchover of the measuring unit between C and T . OLED screen displays real-time temperature value and switch status. It is with flexible installation, easy operation and simple menu. MTM5881 is safe and stable, and it can be widely used in industries such as water utilities, petrochemical, metallurgy, transport, electricity, machinery manufacturing etc. Specifications Power supply: 24V DC Range: -50C~150C Accuracy: <±1“C (FS<100C), <±2°C(FS>100°C) Screen display: OLED with resolution 128*32 white readings in black ground Solution Display refresh time: 1s, 0.5s, 0.2s(default) Repeatability: <±0.1%FS Switch setting: 0.5%FS~99.5%FS Switch delay: 0.0s~99.9s Weight: around 280g Protection: IP67 Impact: < 50g/11ms (GB/T 2423.5-1995) Media compatibility: The gas or liquid which is compatible with stainless steel Vibration: < 20g/10Hz...500Hz (GB/T 2423.10-2008) Transistor output: 2-way PNP or 2-way NPN Switch current: <0.4A Analog output: 4mA~20mA DC; load resistance: <560^ Relay output: one-way (SPDT) Switch voltage: < 250VAC/30VDC Switch current: < 3A Life: 10,000,000 times/min. load, 100,000 times/max. load Media temperature: -50°C~150°C/-58°F~302T Storage temperature: -40°C~80°C/-40F~176F Environmental temperature: -20°C~80°C/-4F~176F Electromagnetism compatibility: GB/T 17626.2/3-2006, GB/T 17626.4-2008 MICRO SENSOR CO.,LTD
