For safety reasons, use only original spare parts from Testo. Any additional work must only be carried out by authorised personnel. Testo will otherwise refuse to accept responsibility for the proper functioning of the instrument after repair and for the validity of certifications. -
Page 6: Product Description
2. Product description The low-cost flow transmitter can be combined with the standard flow probes of the reference class (see table on page 8). Vane, hot ball and hot wire probes can be connected. The device will then be configured for all standard applications in heating, ventilation and air-conditioning. -
Page 7: Advantages Of The Flow Transmitter
4. Advantages of the flow transmitter - Optimal price/performance ratio - electronics immune to interference thanks to reverse voltage protection, surge protection, EMC to industrial standards - Electrical isolation between supply voltage and analogue output - Standard flow sensors can be connected - Easy to install - Flexible analogue outputs and scaling - Two analogue outputs (1 - flow and 2 - temperature (optional)) -

Page 11: Connection
In the 4-wire system the device is supplied via a separate voltage supply (24 V DC). The outputs then actively supply the respective current or voltage signal. In the testo flow transmitter the power supply is galvanically isolated from the analogue outputs. 9.2 Current/voltage measurement (4-wire system) For other 24 V DC max. -
