THERMASGARD® TM 65 - Modbus RJ12
Collect
Calibratable THERMASGARD® TM 65 - Modbus temperature measuring transducer with straight protective tube, Modbus connection, terminal box housing made of impact resistant plastic, housing cover with quick-locking screws, with/without optional display (for indicating the actual temperature). The sensor device is used for detecting temperatures in liquid or gaseous media. Stainless steel thermowells are available as accessory for aggressive media. Applications of the TM-65 can be found in piping systems, heating technology, storage tanks, district heating compact stations, hot-water and cold-water systems, oil and lubricant circulation systems, mechanical, equipment and plant engineering as well as throughout industry. The temperature measuring transducers are factory-calibrated. Adjustment/Fine-tuning by the user is possible (zero-point offset is adjustable). Voltage supply 24 V AC (± 20 %) and 15…36 V DC Power consumption < 1,0 VA/ 24 V DC < 2,2 VA/ 24 V AC Temperature deviation typically ± 0.2 K at +25 °C Sensor Pt1000, DIN EN 60751, class B (Perfect Sensor Protection) Measuring range –50...+150 °C Zero point offset ± 10 °C Ambient temperature Measuring transducer –30...+70 °C Medium depending on selected immersion sleeve Error detection sensor breakage, sensor short circuit Bus protocol Modbus (RTU mode), address range 0...247 selectable Signal filtering 0,3 s / 1 s / 10 s Connection RJ12 plug Protective tube stainless steel, 1.4571, V4A, Ø = 6 mm Permissible air humidity < 95 % r. H., non-precipitating air Protection class III (according to EN 60 730) Protection type IP 65 (according to EN 60 529)* Standards CE conformity, electromagnetic compatibility according to EN 61326, according to EMC Directive 2014/ 30/ EU |
