Page 2: Sensor Specifications
PyroMiniBus non-contact infrared sensors measure temperatures from -20°C to 1000°C and provide an RS485 Modbus RTU interface. The sensors are capable of being used in ambient temperatures up to 120°C without cooling (XCF models: 70°C). They may be connected directly to third-party Modbus Masters, and they are compatible with the optional PM180 6-channel touch screen interface, which provides temperature display, data logging, alarms and analogue outputs. - Page 3 DIMENSIONS Removable spigot Mounting Nut Air Purge Collar 1/8" BSP fitted to type APSN (included) air fitting Sensing Head for use with -201 Thread M16 and -XCF models. Ø 18 Ø 18.6 x 1 mm Not fitted to type APSW for -21 models.

Page 4: Installation
INSTALLATION The installation process consists of the following stages: • Preparation • Mechanical installation • Electrical installation Please read the following sections thoroughly before proceeding with the installation. PREPARATION Ensure that the sensor is positioned so that it is focused on the target only. DISTANCE AND SPOT SIZE The size of the area (spot size) to be measured determines the distance between the sensor and the target. -

WIRING Check the distance between the sensor and the Modbus Master. If necessary, the sensor can be ordered with a longer cable attached. POWER SUPPLY Be sure to use a 24 V DC power supply. The maximum current draw is 50 mA per sensor. MECHANICAL INSTALLATION All sensors come with a 1 m cable and a mounting nut. -

example, it is in the same room). In this case, Reflected Energy Compensation should remain Disabled for an accurate measurement. However, if the sensor is positioned outside an oven or furnace, with the target object inside, the reflection of the hot furnace interior can affect the measurement. In this case, Reflected Energy Compensation should be turned ON and Reflected Temperature should be set to the temperature inside the oven or furnace. - Page 10 Calex infrared temperature sensors.

Page 11: Data Logging
DATA LOGGING With an optional MicroSD Card installed in the slot inside the PM180, data logging may be manually started and stopped via a button on the temperature display screen, or scheduled to begin at a pre-determined time via the Settings menu. If the PM180 is connected via the slave interface to another Modbus network, logging may also be started remotely by the Modbus Master on that network. -
