Page 2: Product Identification
Design and Function Based on a supply voltage of 24 V the PTR 225, PTR 225 S or PTR 237 generates the internal supply voltages required for operation of the integrated Penning mea- surement system. The PTR 225, PTR 225 S or PTR 237 supplies a logarithmic representation of the vacuum pressure by way of a voltage signal which ranges from 0.66 V to 10 V. -
Page 3: Scope Of Delivery
The PTR 225 S Penning gauge is equipped with an adjustable switching threshold. The switching element is a relay. The status of the threshold is indicated by a LED. -
