Electro-pneumatic pressure regulator
Type 1500 Marsh Bellofram

The Marsh Bellofram Type 1500 zero-based panel mounted electro-pneumatic pressure transducer is designed to provide low-cost precision control with low air consumption, in support of valve actuation and positioning, HVAC systems monitoring, material handling systems monitoring, final control elements, pulp and paper handling controls, liquid and gas processing systems, automation systems and other high-flow industrial monitoring and control requirements.

The compact size and accessibility of the Type 1500 to its supply and output ports on the front and back of the unit, allow it to be installed within space-constrained locations or in a manifold for effective control of multiple devices. Units also offer external zero and span adjustments, as well as a field-accessible orifice, for ease of service and repair.

Four uniquely available zero-based range output options include 0-15 psig (0-1.0 BAR), 0-30 psig (0-2.1 BAR), 0-60 psig (0-4.1 BAR) and 0-120 psig (0-8.3 BAR). These units offer hysteresis of less than 1.0% of span, with repeatability of <0.5% of span. An integral pneumatic volume booster is included to provide high flow capacity. Available port sizes include ¼" NPT, BSPT and BSPP. Available electrical connection options include ½" NPT or BPST, as well as conduit terminal block and DIN 43 650-A connectors. The electrical conduit connection meets CE requirements. This unit is also available in FM and CSA approved ATEX intrinsically safe versions, as well as a NEMA 4X version (CSA and FM approved; excludes terminal block). DIN rail and manifold assemblies are available in kits that provide three, five or ten mounting points.
