Maintenance calibrator AR915.B
- two modes of operation: temperature adjustment or temperature measurement, operational mode selection via keyboard
- universal input/output:
- thermoresistance: Pt100, Ni100, in the measurements - automatic detection of a 2- or 3-wire connection of the sensor with line resistance compensation
- thermocouple: J, K, S, B, R, T, E, N, automatic or constant compensation of temperature of the reference junction
- linear (analogue): voltage (mV), resistance
- NOTE: simulation of Pt100, Ni100 sensors and resistance works for continuous (not pulsed) polarization currents of the measurement inputs
- setting the output value directly in °C or in physical units (Ω, mV)
- ergonomic hand-held, pocket housing with small dimensions and low weight, rubberised non-slip side grips
- simple and reliable banana connectors for laboratory use
- highly visible LCD display (without backlighting) and functional keyboard
- power supply from two AA batteries (R6)
- very long operation with a new batter set
- auto shut-off of the calibrator after a specified time of inactivity
- option of testing measurement devices and temperature sensors
- diagnostic functions facilitate the detection of defects in the tested system, such as:
- no polarization current for resistive sensor or its value to high (in the simulation)
- short circuit in the system measuring voltage signal (in the simulation)
- short circuit or open sensor circuit (in measurements)
- quick and easy to readout:
- the type of the set temperature sensor
- the operation direction (input/output)
- of polarization current for resistance sensor (in the simulation)
- the type of detected connection for the resistance sensor (2-, 3-wire)
- the temperature of the reference junction for a thermocouple sensor
- low charging level battery or rechargeable batteries
- Programmable range and step changes of output signal and other configuration parameters such as: display resolution, zero calibration, and amplification of the measured or setpoint signal, keypad lock, calibrator auto-off time, etc.
- option of protecting access to the configuration of parameters with password
- high resistance to interference occurring in industrial environments
- auto power off when battery charge level is too low
- dimensions: 136 x 80 x 25 mm
- ingress protection rating: IP43
- weight: 130 g (excluding batteries) 165g (with batteries)
- operating temperature range: 0 ÷ 50°C
- relative humidity range: 0 ÷ 90 % (no condensation)
